What a dropped stitch is and why it happens
A dropped stitch is a loop of yarn that has slipped off your needle entirely. It looks like a small hole or run in your fabric, similar to a ladder in a stocking. The stitch unravels downward from where it fell, and the more rows you knit past it without noticing, the longer the run becomes.
Dropped stitches happen most often when you're working quickly, when you accidentally pull yarn too tight as you move between stitches, or when a stitch straightforward slides off the end of a needle. They're one of the most common mistakes in knitting, and the good news is that they're fixable—even if you don't notice right away.
Key Takeaways
- A dropped stitch is a loop that has fallen off your needle and creates a visible run or hole in your knitting.
- You can pick up a single dropped stitch using a crochet hook, which is faster and easier than using a knitting needle.
- If the stitch has dropped several rows down, you'll need to pull the loose yarn back up through each row to restore the stitch.
- Prevent dropped stitches by keeping even tension, being careful when moving stitches between needles, and checking your work regularly.
How to pick up a dropped stitch with a crochet hook
The easiest way to fix a dropped stitch is with a crochet hook that matches or is slightly smaller than your knitting needle size. This method works whether the stitch dropped one row ago or several rows back.
First, locate the dropped stitch and identify which row it fell from. Insert the crochet hook through the dropped loop from front to back. You should now see a horizontal strand of yarn above the hook—this is the yarn from the row above. Pull that strand through the loop on your hook. Repeat this process for each row the stitch has dropped, pulling the horizontal strand through the loop each time, until you reach the current row. Once you've worked your way back up, transfer the loop from the crochet hook back onto your knitting needle.
If the dropped stitch is in a purl stitch rather than a knit stitch, the process is the same, but you may find it easier to insert the hook from back to front instead of front to back. The direction doesn't change the outcome—it just makes the motion feel more natural depending on which way the stitch is facing.
Picking up a dropped stitch with a knitting needle
You can also use a spare knitting needle in the same size as your working needles, though a crochet hook is generally faster. Insert the needle through the dropped loop from front to back, just as you would with a crochet hook. Pull the horizontal strand of yarn from the row above through the loop, then repeat for each row the stitch has dropped.
The main difference is that a knitting needle is wider and blunter than a crochet hook, so it can feel less precise. However, if you don't have a crochet hook nearby and you need to fix the stitch when ready, a needle works fine. Once the stitch is restored, transfer it back onto your main working needle.
What to do if the stitch has dropped multiple rows
If you don't notice a dropped stitch until several rows later, don't panic. The process is identical—you just repeat the pull-through motion more times. Count the rows between where the stitch fell and your current row, and pull the horizontal strand through the loop once for each row.
The longer the run, the more yarn you'll be working with, and the strand may feel loose or stretchy. This is normal. Once you've pulled it all the way back up to the current row, the tension usually evens out as you continue knitting. If the restored stitch looks noticeably looser than the stitches around it, you can gently tighten it by pulling on the working yarn slightly as you knit the next few rows.
Preventing dropped stitches in the first place
The best fix is to avoid dropping stitches. Keep your tension consistent—not so tight that you're straining, but not so loose that stitches slide around on the needle. Pay special attention when you're moving stitches from one needle to another or when you're picking up stitches from a cast-on edge.
Check your work every few rows by looking at the fabric itself, not just the stitches on your needle. A dropped stitch is much easier to fix when you catch it right away. If you're a newer knitter, counting your stitches at the end of each row can help you spot a dropped stitch before you've knitted past it.
Use needle stoppers or rubber bands on the ends of your needles if stitches keep sliding off. Some knitters also prefer needles with sharper points or needles made from bamboo or wood, which have more grip than metal needles.
When to unravel and start over instead
Most dropped stitches are worth fixing in place, but there are situations where it's faster to unravel back to the mistake and reknit. If the dropped stitch is in a complex stitch pattern—like a cable or a lace pattern—and you're not confident in restoring it correctly, unraveling may be the safer choice. You'll know the stitches are correct because you'll be knitting them fresh.
If the dropped stitch is only a row or two back and you haven't knitted much past it, unraveling takes just a few seconds. If it's ten rows back, picking it up with a crochet hook is almost always faster. Trust your judgment based on how far back the mistake is and how confident you feel about the stitch pattern.
Frequently Asked Questions
Can I pick up a dropped stitch if I've already bound off?
Yes, but it's more involved. You'll need to unravel the bound-off edge back to the dropped stitch, pick it up, and then reknit and rebind off. If the dropped stitch is only a few stitches from the edge, it's usually worth doing. If it's in the middle of a finished piece, you may decide the small hole is acceptable and leave it.
What if I pick up the stitch wrong and it twists?
If the stitch looks twisted after you've put it back on the needle, straightforward slip it off, untwist it, and put it back on. You can also knit into the back of the stitch on the next row to correct a twist, though this creates a slightly different texture in that one stitch.
Does the size of the crochet hook matter?
A hook that matches your needle size or is one size smaller works best. A hook that's too large may split the yarn, and one that's too small can be hard to work with. If you don't have an exact match, go slightly smaller rather than larger.
Why does my picked-up stitch look looser than the others?
When you pull yarn through multiple rows, the restored stitch naturally has more yarn in it than the surrounding stitches. This evens out as you knit the next few rows. If it's still noticeably loose after a few rows, gently tighten the working yarn as you knit past it.
