Quick fix: Pick up the dropped stitch straight up as a regular knit stitch first, then use a cable needle to re-cross at the correct crossing row. Stabilize before you twist.
What you are seeing
A loose stitch running down through a twisted cable column. If the drop happened through a crossing row, the cable twist will look tangled or uneven at that point.
Why it happens
- A stitch fell off the cable needle during a crossing transfer
- Working the cable crossing too quickly, losing grip on the held stitches
- Loose tension at the base of the cable
Fix it now
- Stop immediately — do not tug the yarn or the ladders will tighten.
- Insert a crochet hook from front to back through the dropped loop.
- Work the stitch straight up each ladder as a knit stitch until you reach the crossing row.
- At the crossing row, identify the two stitches that need to swap. Place them onto a cable needle.
- Re-cross as the pattern specifies (hold front or back), then knit across.
- Continue picking up any remaining bars above the crossing until the stitch is level with your needle.
- Return the stitch to the needle and resume the pattern.
Prevent it next time
- Use a cable needle with a curve or stopper so stitches cannot slide off during the crossing.
- Keep the cable needle within 1 cm of the left needle tip during transfer.
- Mark cable crossing rows with a locking marker so you always know where re-crossings belong.
