Quick fix: Drop the twisted stitch down to where it was worked, and re-knit it through the correct leg (the front/right leg) using a crochet hook.
What you are seeing
Some stitches in your lace look closed or tight compared to their neighbors — the eyelets nearby appear smaller or the stitches pull sideways. When a stitch is twisted (knitted through the back loop accidentally), it creates a tighter, more twisted column that disrupts the airy look of lace.
Why it happens
- Knitting through the back loop (TBL) accidentally on a stitch that should be worked normally
- Yarn overs mounted incorrectly: if you wrap the yarn over the wrong way, the resulting stitch sits backwards on the needle and will twist when knitted
- Picking up a dropped stitch and replacing it backwards on the needle
Fix it now
- Identify the twisted stitch — it will look noticeably tighter and more "wound" than its neighbors.
- Drop that stitch off the needle intentionally and let it ladder down one row.
- Check the stitch orientation: the right leg of the loop should sit at the front of the needle when you're ready to re-knit.
- Use a crochet hook to pull the working loop through the front of the stitch (not the back) to re-knit it correctly.
- Place the corrected stitch back on the needle with the right leg at the front.
Prevent it next time
- After every yarn over, check that the new loop sits with its right leg at the front of the needle
- When picking up a dropped stitch, always check orientation before placing it back on the needle
- If your pattern has intentional twisted stitches (TBL), mark those stitches on your chart so you don't confuse them with accidental twists
