What a dropped stitch is and why it happens

A dropped stitch is a loop of yarn that has slipped off your knitting needle. 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, creating a visible flaw that gets worse the longer you leave it.

Dropped stitches happen most often when you're working quickly, when you accidentally pull yarn too tight on one side, or when a needle slips out of your work. They can also occur if you're using needles that are too small for your yarn or if you're distracted mid-row. The good news is that picking up a dropped stitch is a learnable skill that takes about two minutes once you know the technique.

Key Takeaways

  • A dropped stitch creates a visible run or hole in your knitting and must be picked up before you continue, or it will unravel further down the fabric.
  • Use a crochet hook one size smaller than your knitting needles to pick up the dropped stitch, working from the bottom of the run upward.
  • For each row the stitch has dropped, you hook the yarn and pull it through the loop on your hook, recreating the stitch structure row by row.
  • Once the dropped stitch is picked up to the current row, slip it back onto your knitting needle and continue working normally.
  • If you notice a dropped stitch several rows down, stop and fix it when ready rather than continuing to knit, because the damage spreads downward with each new row.

Gather a crochet hook and locate the dropped stitch

Before you start, find a crochet hook that is one size smaller than your knitting needles. If your needles are US size 8, use a size F (3.75 mm) crochet hook. The smaller hook gives you better control and prevents you from accidentally picking up extra yarn.

Look at your knitting and find the dropped stitch. It will appear as a vertical run or ladder of loose loops hanging below a gap in your fabric. Once you spot it, count how many rows it has dropped. If the stitch fell three rows ago, you will see three horizontal bars of yarn running down from the gap. Stop knitting when ready—do not work another row, because each new row makes the run longer and harder to fix.

Pick up the stitch from the bottom row

Hold your knitting so the dropped stitch faces you. Insert the crochet hook through the lowest loop of the dropped stitch from front to back. The hook should go under the loop, not over it.

Look above that loop and find the first horizontal bar of yarn (the strand that was created when you knitted the row above the dropped stitch). Hook this bar with your crochet hook and pull it down through the loop on your hook. You now have one new loop on your hook. This recreates the stitch for that row.

Repeat this process for each row the stitch has dropped. Hook the next horizontal bar above and pull it through the loop on your hook. Keep going until you reach the top—the current row you were knitting on. You should now have a complete stitch on your crochet hook that matches the structure of the stitches around it.

Return the stitch to your knitting needle

Once the dropped stitch is fully picked up and sitting on your crochet hook, slip it onto your knitting needle. Make sure it sits in the correct position on the needle—it should be in the same column where it fell, between the stitches on either side.

Check that the stitch is oriented correctly. The loop should face the same direction as the other stitches on your needle. If it looks twisted or backwards, slip it off and reorient it before continuing. A twisted stitch will create a distorted appearance in your fabric.

Continue knitting after picking up the stitch

Once the stitch is back on your needle, you can resume knitting normally. Treat it like any other stitch—knit or purl it according to your pattern. You may notice the picked-up stitch looks slightly different from the surrounding stitches for one or two rows, but this evens out as you work more rows above it.

If you're working in the middle of a row when you notice the dropped stitch, you have two options. You can pick it up when ready and then continue with the stitches you were working on. Or, if the stitch is far to the left of where you are now, you can finish the current row, then go back and pick it up on the next row. Either way, do not leave a dropped stitch unattended for more than one row.

Prevent dropped stitches while you work

The easiest fix is to avoid dropping stitches in the first place. Keep your tension even—not too tight, which stresses the yarn, and not too loose, which lets stitches slip off. If you're new to knitting, work at a slower pace until you develop muscle memory for consistent tension.

Make sure your needles are the correct size for your yarn. Needles that are too small make it harder to work stitches and easier to accidentally pull them off. Check your yarn label for the recommended needle size, and use that as your starting point.

When you set your knitting down, find your stitches. If you're stopping mid-row, insert a stitch marker or a spare needle through the working stitches to keep them from sliding off. Some knitters wrap a rubber band loosely around the needle ends. These small steps prevent the frustration of picking up multiple dropped stitches when you pick your project back up.

What to do if the stitch has dropped many rows

If you don't notice a dropped stitch until it has fallen five or more rows, the process is the same—you still use a crochet hook and work from bottom to top. However, the run will be more visible in your finished fabric, and you may see a slight widening or looseness in that column of stitches.

For a dropped stitch that has fallen very far, some knitters choose to use a lifeline to prevent further damage. A lifeline is a piece of yarn threaded through all the stitches on your needle at a specific row. If you drop a stitch below the lifeline, you can unravel back to the lifeline and pick up all the stitches at once, rather than fixing them individually. This is more common in complex colorwork or lace patterns where dropped stitches are harder to spot.

Frequently Asked Questions

What if I can't find the dropped stitch right away?

Look for a vertical line or ladder running down your fabric, or a hole where stitches should be. Run your finger across each row from left to right—you'll feel the gap where the stitch is missing. If you still can't spot it, hold your knitting up to the light and look for a break in the stitch pattern.

Can I pick up a dropped stitch with my knitting needle instead of a crochet hook?

You can, but a crochet hook is easier because it has a curved end that catches yarn more reliably. Knitting needles are straight and pointed, which makes it harder to hook the horizontal bars without accidentally splitting the yarn. A crochet hook is inexpensive and worth having on hand.

What if I pick up the stitch but it looks twisted or loose?

Slip it back off your needle and try again. Make sure you're pulling the horizontal bars through in the correct direction—from front to back, not back to front. If the stitch still looks wrong after you pick it up, you can also unravel that one stitch and redo it by hand once it's back on the needle.

Will a picked-up stitch be visible in the finished knitting?

Usually not, especially after you've worked several more rows above it. The picked-up stitch may look slightly different for one or two rows, but blocking (wet-blocking or steam-blocking) your finished project will even out the tension and make the repair nearly invisible.

Can I prevent dropped stitches by using needle stoppers?

Yes. Needle stoppers (also called needle caps or point protectors) are small rubber or plastic covers that fit over the ends of your needles. They keep stitches from sliding off when you set your work down. They're especially useful if you knit on the go or have cats or children who might disturb your project.
