How to Fixing a Dropped Stitch (Knitting)

A dropped stitch — one that's slipped off the needle unworked and starts unraveling down through the rows below it — is one of the most common small emergencies in knitting, and one of the most fixable, provided it's caught before it runs too far. The stitch doesn't actually disappear; it runs down as a "ladder" of horizontal bars, each one representing a row the stitch dropped through, and every one of those bars can be recovered.

Stopping the run immediately

The very first move, before anything else, is to stop the stitch from running any further — slip a locking stitch marker, a safety pin, or even a bobby pin directly through the live loop at the bottom of the run to anchor it in place while you find a crochet hook and assess how far it's actually traveled.

Laddering it back up with a crochet hook

1. Insert a crochet hook (a size close to your working needle size) through the live loop from the front.
2. Identify the first horizontal bar directly above the loop — this is the "rung" from the row just above.
3. Catch that bar with the hook and pull it through the loop on the hook, forming a new loop.
4. Repeat for each successive bar, working upward one row at a time, until you reach the current working row.
5. Place the final loop back onto the knitting needle in the correct orientation (not twisted) and continue.

Knit side versus purl side

A dropped stitch on a stockinette knit row is laddered up from the front, as described above, and each bar sits behind the loop as you climb. On a purl row, the same principle applies but from the opposite face — many knitters find it easier to flip the work to the knit side and ladder the stitch up from there regardless of which side it dropped on, since knit-side laddering is generally the more intuitive motion to track visually.

Where it goes wrong

The stitch ends up twisted once it's back on the needle. A very common issue — an untwisted stitch sits with its right leg in front of the needle; a twisted one has the legs reversed. Check the final stitch's orientation carefully against its neighbors before continuing, and untwist it (slip it off, turn it, and put it back on correctly) if it doesn't match.

Running out of "rungs" partway up, with the stitch still not reaching the needle. Means the stitch ran further than initially assessed, sometimes through several more rows than expected — recount the bars available before laddering, and if the run genuinely extends further than you can safely see or reach, it may be faster to unravel back to below the drop entirely and reknit that section from scratch rather than trying to chase a very long ladder.

A visible loose or tight spot at the repaired stitch even after laddering it up correctly. The laddered stitch sometimes sits at a slightly different tension than its neighbors immediately after repair — a light block or steam, or simply working a few more rows and letting the fabric settle, usually evens this out; it's rarely a sign the repair itself was done wrong.

Dropped stitches in a textured or patterned stitch

Laddering works cleanly for plain stockinette because every bar is identical and unambiguous. In a textured stitch pattern (cables, lace, colorwork), a dropped stitch is considerably harder to ladder correctly, since the "rungs" available may not be simple straight bars, and the surrounding pattern needs to be tracked carefully to avoid laddering the stitch back up in the wrong stitch pattern. For a dropped stitch in a complex pattern section, many knitters prefer to tink (unknit stitch by stitch) back to before the drop and reknit that section correctly, rather than attempting to ladder through unfamiliar territory.

Prevention: catching a drop before it becomes a problem

Most drops happen from a stitch sliding off an unattended needle tip (common with slippery yarn or metal needles) or from a stitch being missed during a fast, distracted knitting session. Checking your stitch count periodically against the pattern, and using needle tip protectors or a project bag that keeps needles from jostling loose in transit, both meaningfully reduce how often a stitch drops unnoticed in the first place.

FAQ

Does a crochet hook need to be a specific size to fix a dropped stitch? Roughly matching your working needle's size works well — too small a hook struggles to grab the bars cleanly, and too large a hook can stretch the repaired stitches out of proportion with their neighbors; a hook a size or so smaller than the needle is a common practical choice.

How far can a stitch run before it's unfixable by laddering? There's no hard limit, but practically, a run of many rows becomes increasingly fiddly and error-prone to ladder correctly — for a very long run, comparing the time cost of careful laddering against simply unraveling to below the drop and reknitting is often the more realistic call.

Can a dropped stitch be fixed after the piece has already been blocked? Yes, though it's more awkward on a blocked, dry piece than on live work — the same laddering technique applies, just working more carefully since the fabric is set into its blocked shape rather than sitting loosely on active needles.
