You’re working on a scarf, sweater, or blanket when you notice something unexpected. There’s a small hole in your knitting, and somehow you have one more stitch on your needle than the pattern calls for. You haven’t deliberately increased, so where did that extra stitch come from?
One of the most common explanations is an accidental yarn over.
A yarn over happens when the working yarn passes over a knitting needle, creating a new loop. When done intentionally, it’s a useful technique for making decorative holes in lace patterns or increasing the number of stitches. When it happens by mistake, however, it can create an unwanted opening and gradually make your knitting wider than intended.
Fortunately, an accidental yarn over is usually easy to fix when you catch it quickly. In many cases, you can simply remove the extra loop without unraveling your work.
If you’ve already knitted several rows beyond the mistake, the repair may require a little more attention, but you still have options.
Here’s how to recognize an accidental yarn over, remove the unwanted stitch, repair the resulting hole, and prevent the same mistake from happening again.
🧶 What Is an Accidental Yarn Over?
An accidental yarn over occurs when the working yarn wraps over the knitting needle and creates an additional loop that wasn’t required by the pattern.
In ordinary knitting, the working yarn moves between stitches without creating a new stitch unless you deliberately perform an increase.
However, if the yarn passes over the needle at the wrong moment, it can leave an extra loop sitting between two regular stitches.
If you knit or purl into that loop on the following row, it becomes an additional stitch in your fabric.
Because a yarn over doesn’t pass through a stitch from the previous row, it also creates a small opening beneath the new stitch.
This opening is called an eyelet.
When you’re knitting lace, eyelets are often intentional decorative features. In plain stockinette, garter stitch, or ordinary ribbing, they may indicate a mistake.
For example, suppose you’re knitting a scarf with 30 stitches in every row. If you accidentally create a yarn over and then work into it on the next row, you’ll have 31 stitches.
If the mistake happens repeatedly, the scarf may gradually become wider.
Understanding how the extra loop was created makes it much easier to correct the problem before it affects the rest of your project.
🔍 How to Tell If You’ve Made an Accidental Yarn Over
The most obvious sign of an accidental yarn over is an extra stitch accompanied by a small hole in the fabric.
In stockinette stitch, the opening usually appears between two columns of V-shaped knit stitches.
If you’ve already knitted several rows above the mistake, you may notice an additional column of stitches beginning directly above the hole.
This distinguishes an accidental yarn over from a dropped stitch.
A dropped stitch usually causes the stitch count to decrease and may create a vertical ladder of loose yarn strands. An accidental yarn over increases the stitch count and can create an additional column.
According to TECHknitting, an accidental yarn over commonly produces an opening that is somewhat rounded and wider near the top, with a new column of knitting emerging above it.
Another useful clue is the stitch count.
If your pattern requires 40 stitches but your needle now contains 41, look for an unexpected loop or hole.
However, not every extra stitch is caused by a yarn over. Accidentally knitting into the strand between two stitches or working the same stitch twice can also create an increase.
Look closely at the structure of the fabric before deciding how to repair it.
🪡 Why Do Accidental Yarn Overs Happen?
Accidental yarn overs most commonly occur when changing between knit and purl stitches.
When knitting a standard knit stitch, the working yarn should usually be behind the needles. When purling, it should be in front.
Moving between these two positions is part of ordinary knitting, but the direction in which the yarn travels matters.
The yarn should move between the needle tips rather than over the top of the needle.
If you bring the yarn forward to purl and then forget to return it to the back before knitting, it may wrap over the needle and create an extra loop.
The same problem can occur when moving from a knit stitch to a purl stitch if you carry the yarn around the needle instead of between the tips.
Ribbing and seed stitch are especially common places for this mistake because they require frequent changes between knit and purl stitches.
Accidental yarn overs can also happen at the beginning of a row.
Sometimes the working yarn is accidentally pulled over the needle while turning the project, making the first stitch appear as though it consists of two separate loops.
If both loops are worked as stitches, you may accidentally increase at the edge.
Once you recognize these situations, preventing unwanted yarn overs becomes much easier.
🛠️ How to Fix an Accidental Yarn Over on the Same Row
If you notice the accidental yarn over before finishing the row, the repair is usually straightforward.
Because the extra loop hasn’t yet been worked into the next row, it can often be removed without leaving a noticeable mark.
Step 1: Find the Extra Loop
Stop knitting when you notice the problem and examine the stitches on your needle.
An accidental yarn over often looks like a loose strand or loop sitting between two regular stitches.
Unlike an ordinary stitch, it doesn’t have the same connection to the fabric directly beneath it.
Compare the stitches with the surrounding knitting to determine which loop doesn’t belong.
If you’re following a pattern, check the instructions to confirm that an increase wasn’t required at that point.
Step 2: Undo the Stitches If Necessary
If you’ve already worked several stitches beyond the accidental yarn over, carefully undo those stitches until you reach it.
This technique is called tinking, which simply means reversing your knitting one stitch at a time.
To tink, insert the left needle into the stitch from the previous row before releasing the newer stitch from the right needle.
Gently pull the working yarn free, leaving the original stitch secured on the left needle.
Repeat until you’ve reached the unwanted loop.
For a more detailed explanation, see How to Undo Knitting Without Losing Stitches.
Step 3: Remove the Accidental Yarn Over
Once the unwanted yarn-over loop is accessible, allow it to slip off the needle.
Because it was created by wrapping the working yarn over the needle rather than knitting into a previous stitch, it should release without unraveling an established column of knitting.
Check that the surrounding stitches remain securely on the needle.
The yarn that formed the extra loop will return to the strand connecting the neighboring stitches.
Step 4: Position the Working Yarn Correctly
Before continuing, make sure the working yarn is in the correct position for your next stitch.
For an ordinary knit stitch, the yarn should be at the back.
For an ordinary purl stitch, it should be at the front.
Move the yarn between the needle tips rather than wrapping it over the needle.
Continue knitting according to the pattern, then count your stitches to confirm that the extra loop has been removed.
🧵 How to Fix an Accidental Yarn Over on the Next Row
If you discover an accidental yarn over while working the following row, the mistake is still relatively easy to repair.
At this stage, the extra loop is sitting on your needle, but it hasn’t yet been incorporated into a new stitch.
Begin by knitting or purling normally until you reach the unwanted yarn over.
Look carefully at the loop before working it.
An accidental yarn over usually appears as a strand crossing the needle without emerging from an ordinary stitch in the row beneath it.
If you’re certain the loop is an accidental yarn over rather than an intentional increase, slide it off the left needle without knitting or purling into it.
The extra loop will release, and the yarn will become part of the strand connecting the neighboring stitches.
Continue working the row normally.
When you reach the end, check your stitch count. You should now have the number required by the pattern, assuming there aren’t other errors.
The spot where you dropped the yarn over may look slightly loose because the extra yarn has been redistributed into the adjacent stitches.
Gently adjusting the surrounding fabric can help even out the tension.
This approach is recommended in knitting tutorials from Knitting.com and Interweave because it removes the accidental increase before it becomes incorporated into the fabric.
However, it’s important to distinguish an accidental yarn over from an intended decorative eyelet. If your pattern specifically calls for a yarn over at that location, dropping it would remove a necessary stitch.
⏳ How to Fix an Accidental Yarn Over Several Rows Down
An accidental yarn over becomes more complicated to repair after you’ve knitted several rows above it.
When you work into the extra loop, you turn it into a regular stitch. Each subsequent row adds another stitch to that column, causing the extra stitch to become part of the fabric.
The original hole remains at the bottom of the column.
There are several ways to address the problem, but the best choice depends on how far back the mistake occurred and how important it is to preserve the exact stitch pattern.
Option 1: Undo the Rows and Remove the Yarn Over
For an accurate repair, unraveling back to the mistake is usually the most reliable method.
This is especially true if the yarn over occurred in a garment, lace pattern, or another project where stitch counts and shaping need to be precise.
Before unraveling, place a lifeline through a correct row beneath the mistake.
A lifeline is a length of smooth yarn or thread passed through the stitches of an existing row. It prevents the knitting from unraveling beyond that point.
Once the stitches are protected, carefully unravel the unwanted rows until you reach the accidental yarn over.
Remove the extra loop and return the correct stitches to your knitting needle.
You can then rework the affected section according to the pattern.
Although this approach takes more time, it restores both the stitch count and the original structure of the fabric.
Option 2: Drop the Extra Column Back to the Yarn Over
If the accidental increase occurred only a few rows earlier, you may be able to remove the extra stitch by dropping its column back to the original yarn over.
First, identify the extra stitch and confirm that it forms a column beginning at the unwanted hole.
Do not confuse it with a stitch that was already part of the fabric before the mistake.
Carefully release the extra stitch from the needle while keeping its neighbors secure.
Allow the stitch to unravel downward through its own column.
The unraveling should stop at the original yarn over because there is no corresponding stitch beneath that point.
You will be left with additional yarn where the extra column used to be.
For a mistake only a couple of rows down, this slack may be small enough to distribute among the surrounding stitches.
Use your fingers or a knitting needle tip to gently ease the extra yarn across nearby stitches.
However, this method becomes less satisfactory as the column gets longer. Removing many rows of extra stitches produces a significant amount of loose yarn that may form visible horizontal strands.
TECHknitting recommends unraveling back to the mistake for the cleanest result when an accidental yarn over has developed into a substantial extra column.
Option 3: Make a Decrease and Leave the Hole
If you’ve already knitted many rows beyond the mistake, you may decide that the original hole isn’t worth repairing.
You can restore the correct stitch count by working a decrease near the extra column.
Depending on the pattern, this might involve knitting two stitches together (k2tog) or making a slip-slip-knit decrease (ssk).
A decrease removes one stitch, bringing the total back to the required number.
However, this doesn’t eliminate the original yarn-over hole or the extra column between the hole and the decrease.
The fabric may still show where the unwanted increase occurred, particularly in smooth stockinette.
This approach is best reserved for situations where the mistake is inconspicuous or doesn’t affect the project’s appearance and construction significantly.
It can be reasonable for a casual scarf or textured blanket, but it may not be suitable for a fitted sweater or a symmetrical lace pattern.
🕳️ How to Fix the Hole Left by an Accidental Yarn Over
An accidental yarn over can leave a hole even after you’ve corrected the stitch count.
If you removed the loop before working it into another row, the opening may close naturally as the extra yarn settles into the surrounding stitches.
However, if the yarn over was worked into the fabric and remained there for several rows, the resulting eyelet may be more noticeable.
The most reliable way to eliminate both the hole and the extra stitch is to undo the knitting to the point where the yarn over occurred.
If you don’t want to unravel, there are a few alternatives.
For a small opening caused by a recently dropped yarn over, gently redistribute the excess yarn into nearby stitches.
Use a knitting needle tip to move some slack from the loose area into neighboring loops, working gradually rather than pulling one stitch tight.
This can help the fabric look more even.
If the hole is deeper in the project, duplicate stitch may help disguise it.
Duplicate stitch involves using a yarn needle and matching yarn to follow the path of existing stitches, recreating the appearance of knitted loops over the affected area.
Carefully worked duplicate stitching can make a small hole less noticeable, although it doesn’t automatically correct the underlying stitch count.
You may still need to decrease elsewhere if the accidental yarn over added a permanent extra stitch.
For heavily patterned knitting or garments where the repair will be visible, unraveling to the mistake usually produces a neater result.
🪡 How to Prevent Accidental Yarn Overs When Switching Between Knit and Purl
The most effective way to prevent accidental yarn overs is to pay attention to how the working yarn moves between the front and back of your knitting.
When changing from a knit stitch to a purl stitch, bring the working yarn forward between the needle tips.
Then work the purl stitch normally.
When changing from a purl stitch to a knit stitch, move the yarn backward between the needle tips before inserting your right needle into the next stitch.
The important detail is that the yarn travels between the needles rather than over the needle itself.
This prevents an extra loop from forming.
You can practice the movement with a small swatch of knit-one, purl-one ribbing.
Cast on a comfortable number of stitches and work slowly, deliberately moving the yarn into position before each stitch.
Watch how the yarn travels from front to back and back to front.
After a few rows, count your stitches.
If the number remains consistent, you’re moving the yarn correctly.
Once the motion becomes familiar, switching between knit and purl stitches will feel much more natural.
📈 Why Does My Knitting Keep Gaining Stitches?
If your knitting gradually becomes wider without any instructions to increase, accidental yarn overs are one of the first things to check.
Suppose your project begins with 25 stitches.
After several rows, you count 27 stitches, even though the pattern calls for a constant width.
That means you’ve added two stitches somewhere along the way.
An accidental yarn over is a likely explanation, especially if your knitting contains small holes or loose loops.
However, there are other possibilities.
Sometimes knitters accidentally work into the strand between two stitches, creating an unintended increase.
Another common problem occurs at the beginning of a row when the working yarn is pulled over the needle, making the first stitch appear as two separate loops.
If both loops are worked, an extra stitch may be created.
To identify the cause, examine where the extra stitch begins.
A yarn over typically produces an eyelet at the base of the new stitch column.
An accidental increase made by knitting into another strand may have a different appearance.
Counting your stitches after every row or pattern repeat can help you catch the problem before it becomes difficult to repair.
If your project is widening unexpectedly, avoid simply making random decreases to compensate. It’s better to identify why the extra stitches are appearing so you can prevent the problem from continuing.
🧣 Can Accidental Yarn Overs Happen in Garter Stitch?
Yes. Accidental yarn overs can happen in garter stitch, even though the pattern may involve nothing more than knitting every row.
One common cause occurs at the beginning of a row.
When you turn your knitting, the working yarn may be hanging in front of the needle.
If you pull it over the needle instead of moving it into the correct position beneath the needle, the first stitch may look like two loops.
Knitting both loops separately can create an accidental increase.
Over several rows, the project may gradually become wider along one edge.
Garter stitch also has a textured surface, so the resulting hole may be less obvious than it would be in smooth stockinette.
If you’re knitting a garter-stitch scarf and notice that the edges are gradually spreading outward, count your stitches and examine the first stitch of each row.
Make sure you’re working into only the intended stitch and not accidentally creating an extra loop.
If you’ve caught the mistake on the current row or the next, removing the unwanted loop may be enough.
If several rows have been worked above it, the same repair choices apply as in other stitch patterns.
🧵 Why Do Accidental Yarn Overs Happen in Ribbing?
Ribbing is one of the most common places for accidental yarn overs because the working yarn frequently moves between the front and back of the fabric.
In knit-one, purl-one ribbing, every stitch requires a change in yarn position.
If you accidentally carry the yarn over the needle rather than between the needle tips, you create a new loop.
The problem can be particularly confusing because ribbing naturally contracts, making some stitches appear closer together than others.
An extra stitch may not become obvious until you’ve completed several rows and notice that the pattern no longer lines up correctly.
For example, in ordinary knit-one, purl-one ribbing, knit stitches should form continuous vertical columns, with purl stitches between them.
If an unwanted yarn over is worked as an extra stitch, the alternating pattern can become disrupted.
To prevent this, slow down when transitioning between knits and purls.
Move the yarn deliberately between the needle tips, then form the next stitch.
If the ribbing pattern suddenly seems incorrect, count the stitches and examine the area where the pattern stopped lining up.
Correcting an accidental yarn over early can prevent the mistake from affecting the remaining rows.
🧩 How to Tell an Accidental Yarn Over From an Intentional One
Not every yarn over is a mistake.
In lace knitting, openwork scarves, shawls, and decorative stitch patterns, yarn overs are deliberately used to create holes and increase the number of stitches.
The abbreviation YO in a knitting pattern usually means yarn over.
A written instruction may ask you to work a yarn over before or after a decrease, creating an eyelet without changing the total stitch count.
For example, a pattern might instruct you to work a yarn over followed by knit two together.
The yarn over adds one stitch, while the decrease removes one.
The total number of stitches remains unchanged, but a decorative hole appears in the fabric.
If you encounter a loose loop while following a lace pattern, check the instructions before dropping it.
Removing an intentional yarn over can disrupt the design and leave you with too few stitches.
In charted lace patterns, yarn overs are commonly represented by an open circle or another symbol explained in the chart key.
The safest approach is to compare your knitting with the written pattern, confirm the expected stitch count, and determine whether the opening belongs in the design.
If the pattern intentionally includes an eyelet at that location, the yarn over should remain.
🪝 Can You Fix an Accidental Yarn Over With a Crochet Hook?
A crochet hook can be useful for certain yarn-over repairs, particularly when you’re working with a mistake that has already developed into an extra column.
However, fixing an accidental yarn over isn’t the same as picking up an ordinary dropped stitch.
When you repair a dropped stitch, you usually rebuild a missing column by pulling horizontal strands through a loop.
With an accidental yarn over, the opposite problem has occurred.
You’ve added a column that shouldn’t exist.
A crochet hook may help you carefully undo the extra column or redistribute small amounts of loose yarn.
It can also be useful when working duplicate-stitch repairs or adjusting the tension around a hole.
However, it won’t automatically remove the extra yarn created by unraveling several rows of an unwanted column.
If the accidental increase occurred many rows earlier, you may still need to unravel the fabric to achieve a neat correction.
A crochet hook is therefore a helpful repair tool, but the correct technique depends on the structure of the mistake.
🛡️ How to Prevent Accidental Yarn Overs in Future Projects
Accidental yarn overs are easier to prevent once you understand why they happen.
One of the most useful habits is checking the position of the working yarn before forming each stitch.
For a standard knit stitch, the yarn should be behind the needles. For a standard purl stitch, it should be in front.
When switching between the two, always move the yarn between the needle tips.
It’s also helpful to examine the first stitch after turning your work.
Make sure the working yarn hasn’t been pulled over the needle in a way that creates a false second stitch.
Counting stitches regularly is another simple way to catch accidental increases.
You don’t necessarily need to count after every row of a complicated project, but checking at the end of a pattern repeat or after several rows can reveal problems before they become significant.
Stitch markers can make counting easier, particularly when working wide projects or repeated stitch patterns.
For example, you can place markers every ten or twenty stitches, making it easier to recognize where an extra stitch has appeared.
Good lighting also matters.
Dark, fuzzy, or highly textured yarn can make unwanted loops difficult to see.
If you’re practicing a new stitch pattern, working with smooth, light-colored yarn makes it easier to identify the structure of each stitch.
Finally, inspect your knitting periodically instead of waiting until the project is nearly finished.
A small hole or unexpected extra stitch is much easier to repair when it’s only one row below your needles.
❓ Frequently Asked Questions
How Do You Fix an Accidental Yarn Over Without Unraveling?
If the accidental yarn over is still on your needle and hasn’t been worked into a stitch, simply let the extra loop slip off the needle.
The additional yarn will become part of the strand between the surrounding stitches. Count your stitches afterward to confirm that the unwanted increase has been removed.
Can You Fix an Accidental Yarn Over Several Rows Down?
Yes, but the repair becomes more complicated when you’ve knitted several rows above the mistake.
You may be able to drop the extra column back to the original yarn over and redistribute the loose yarn if the mistake is relatively recent.
For older mistakes, unraveling back to the yarn over generally produces the cleanest result.
Why Do I Have an Extra Stitch and a Hole in My Knitting?
An extra stitch accompanied by a small hole is a common sign of an accidental yarn over.
The hole forms because the yarn was wrapped over the needle without passing through a stitch beneath it. If you work into that loop on the next row, it becomes an additional stitch.
What Is the Difference Between a Yarn Over and a Dropped Stitch?
A yarn over creates an additional loop and increases the stitch count when that loop is worked. It often creates a decorative or accidental opening in the fabric.
A dropped stitch occurs when an existing stitch slips off the needle and begins unraveling downward, often producing a vertical ladder. It usually reduces the number of stitches remaining on the needle.
Can You Fix an Accidental Yarn Over by Knitting Two Together?
Knitting two stitches together can remove the extra stitch from your current stitch count, but it doesn’t repair the original hole.
If the accidental yarn over occurred several rows earlier, the additional column will remain visible between the hole and the decrease.
This can be an acceptable compromise for an inconspicuous mistake, but unraveling back to the original yarn over provides a more complete correction.
Why Do I Keep Making Accidental Yarn Overs in Ribbing?
Ribbing requires frequent movement of the working yarn between the front and back of the knitting.
If you accidentally carry the yarn over the needle instead of between the needle tips, you can create an unwanted loop.
Slowing down when switching between knit and purl stitches can help prevent the problem.
Will Blocking Close an Accidental Yarn-Over Hole?
Blocking may improve minor tension differences around a recently corrected yarn over, but it generally won’t close a deliberate-sized eyelet that has become part of the knitted fabric.
If the hole remains visible several rows below your needles, you may need to unravel the knitting or carefully disguise the opening with a suitable repair technique.
Should You Always Fix an Accidental Yarn Over?
Not necessarily. The decision depends on the project’s purpose, appearance, and stitch count.
If an accidental yarn over is hidden in a highly textured fabric and doesn’t affect the finished shape, you may decide to leave it.
However, in fitted garments, lace patterns, or projects where stitch counts are important, correcting the mistake is usually worthwhile.
🌿 Final Thoughts
An accidental yarn over is one of the most common reasons knitters discover unwanted holes and extra stitches in their projects.
The mistake usually happens when the working yarn passes over the knitting needle instead of moving between the needle tips, particularly when switching between knit and purl stitches.
Fortunately, catching the problem early makes it easy to correct.
If the unwanted loop is still on your needle, you can usually remove it without unraveling your work. If you’ve already knitted several rows above it, you may need to remove the extra stitch column or unravel back to the original mistake.
The most important thing is to understand how the extra stitch was created before deciding how to repair it.
An accidental yarn over isn’t the same as a dropped stitch, and simply adding a decrease later won’t always remove the resulting hole.
With a little practice, you’ll become better at recognizing unwanted loops before they develop into larger problems.
Moving the yarn between the needle tips, counting your stitches regularly, and checking your work after each pattern repeat can make accidental yarn overs much less frequent.
And when one does happen, you’ll know exactly what to look for and how to get your knitting back on track.
