What a dropped stitch is and why it happens
A dropped stitch is a loop of yarn that has slipped off your needle and is no longer being held in place. 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 hard while inserting your needle, or when you slip a stitch off the needle without meaning to. They also occur when you're learning and your tension is uneven. The good news is that catching and fixing a dropped stitch takes only a few minutes, and the repair is invisible once you're done.
Key Takeaways
- A dropped stitch is a loop that has fallen off your needle and creates a visible run in your knitting that goes downward.
- You can fix a dropped stitch using a crochet hook, which pulls the loose yarn back through each row until the stitch is restored.
- The sooner you notice and fix a dropped stitch, the fewer rows you'll have to work through to restore it.
- If you drop a stitch in stockinette stitch (the most common pattern), the repair is straightforward and leaves no trace.
- Dropped stitches in textured patterns like ribbing or cables require the same technique but demand more attention to which direction the yarn should face.
How to fix a dropped stitch with a crochet hook
The fastest way to fix a dropped stitch is with a crochet hook one size smaller than your knitting needles. Insert the hook through the dropped stitch from front to back, then catch the horizontal strand of yarn that sits directly above it. Pull that strand through the stitch. Repeat this process for each row above the dropped stitch, working upward until you reach the row where the stitch currently sits on your needle.
Once you've pulled the yarn through all the rows, the stitch will be restored and sitting on your crochet hook. Slip it back onto your knitting needle, making sure it faces the correct direction. If you're working in stockinette stitch (knit on the right side, purl on the wrong side), the stitch should sit on the needle with the working yarn on the right side of the loop.
If you don't have a crochet hook, you can use a spare knitting needle of similar size, though a crochet hook's curved end makes the process easier. In a pinch, even a toothpick or a straightened paperclip will work.
Fixing a dropped stitch without a crochet hook
If you have no crochet hook available, use a spare knitting needle or any thin, pointed tool. The technique is identical: insert the tool through the dropped stitch, catch the strand above it, and pull it through. The only difference is that a crochet hook's curve helps you catch the yarn more easily, while a straight needle requires slightly more precision.
Some knitters prefer using their fingers for very recent drops (only one or two rows down). Gently pull the loose yarn upward and work it back through the stitch with your fingers, then place the restored stitch back on the needle. This works best when the yarn is still slack and hasn't tightened.
Fixing a dropped stitch in ribbing or textured patterns
Ribbing alternates knit and purl stitches, so you must pay attention to which direction the yarn faces when you restore the stitch. If the stitch should be a knit stitch, the working yarn should sit behind the needle. If it should be a purl stitch, the yarn should sit in front. Use the pattern of the stitches on either side to determine which type the dropped stitch should be.
In cable patterns, the dropped stitch is still restored the same way—pull the yarn through each row—but you may need to check your pattern notes to may support the stitch sits correctly relative to the cable twist. Most of the time, the stitch will naturally fall into the right position as you pull the yarn through.
For textured stitches like seed stitch or moss stitch, follow the same rule: look at the stitches around the dropped one to determine whether it should face as a knit or purl, then restore it accordingly.
Preventing dropped stitches while you work
The most common cause of dropped stitches is pulling the working yarn too tight as you insert your needle into a stitch. Keep your tension even and relaxed, especially at the moment you're moving a stitch from one needle to the other. A stitch should slide smoothly onto and off your needle without resistance.
When you're learning to knit, work at a slower pace until your hand movements become automatic. Rushing increases the chance that you'll accidentally slip a stitch off the needle. If you're prone to dropping stitches, count your stitches at the end of every few rows—this catches a dropped stitch within a row or two, before it becomes a long run.
Some knitters use stitch markers to divide their work into sections. If you drop a stitch, the marker tells you which section it fell in, so you don't have to search the entire row. Markers are especially useful when you're working on a large project like a sweater or blanket.
What to do if you don't notice a dropped stitch right away
If you've knitted several rows past a dropped stitch, the repair takes longer but works the same way. You'll pull the yarn through more rows, so the process is more tedious, but the end result is identical. Start at the bottom of the run and work upward, pulling one strand through at a time.
If the dropped stitch has unraveled so far that the yarn has separated into individual plies (the thin strands that make up the yarn), you may have a harder time catching it cleanly. In this case, work slowly and use good lighting. If the yarn is very thin or delicate, a crochet hook becomes essential because your fingers alone may not have enough control.
Once the stitch is restored, tighten it gently by pulling the working yarn. The restored stitch may look slightly looser than the stitches around it at first, but it will even out as you knit the next few rows.
When to unravel and start over instead
If a dropped stitch is in a complicated pattern section—such as a cable crossing or a lace motif—and you're not confident in restoring it correctly, you have the option to unravel back to that point and reknit. This takes more time than the crochet hook method, but it guarantees the pattern is correct.
Unraveling is also the better choice if the dropped stitch has been sitting for many rows and the yarn has become tangled or matted. In that case, the yarn may not pull through cleanly, and you risk damaging the fabric by forcing it. Unravel to a few rows above the dropped stitch, place the stitches back on your needle, and reknit from there.
Frequently Asked Questions
How do I know which direction the yarn should face when I put the stitch back on the needle?
Look at the stitches on either side of the dropped stitch. In stockinette stitch, all stitches face the same direction, so match that. In ribbing or textured patterns, look at whether the neighboring stitches are knits or purls, and position your restored stitch to match the pattern. When in doubt, the stitch should sit with the working yarn on the right side of the loop for a knit stitch, and on the left side for a purl stitch.
Can I fix a dropped stitch if I've already cast off?
Yes, but it's more difficult because the yarn is no longer connected to your working yarn. You'll need to carefully unravel the cast-off edge back to the dropped stitch, restore the stitch using the crochet hook method, then recast off. For this reason, it's worth checking your finished piece before you weave in ends.
What if the dropped stitch is at the edge of my work?
Edge stitches (the first and last stitch of each row) can be dropped just like any other stitch. Restore them the same way, but pay extra attention to tension—edge stitches are often looser than interior stitches, so pull the yarn slightly tighter as you work through the rows. The edge will look neater once you've evened out the tension.
Do I need a crochet hook, or can I always use a knitting needle instead?
A crochet hook is easier because its curved end helps you catch the yarn, but a knitting needle works fine. The curve just makes it less likely that you'll accidentally split the yarn or miss the strand you're trying to pull through. If you knit regularly, having a crochet hook in your project bag is worth it.
Will the repair show in the finished piece?
No. Once the stitch is restored and you've knitted a few more rows, the repair is invisible. The fabric will look exactly as if the stitch had never been dropped. The only time a repair might be visible is if the tension around the restored stitch is noticeably different from the surrounding stitches, but this evens out with a little blocking or wear.
