Knitting - Basic Techniques
Both of these methods for repairing without unravelling are techniques especially for stretchy knits. Knitting will be more fun if you know them. Using a crochet hook the same size as your knitting needles, place the fabric on a f lat surface to begin.
If you dropped a stitch
Insert the hook into the dropped stitch, picking up and pulling through the strand of yarn crossing between the adjacent stitches, 1 row at a time. When you reach the top, place the new stitch on the left-hand needle.
If a mis-knit happened several rows down
Drop the stitch vertically above the mis-knit off the left-hand needle. Insert the hook into the fabric 1 row below the mis-knit stitch, then un-knit the stitches down to the hook. Fix the mis-knit stitch, then use the hook to re-knit the stitches up to the needle, and place the stitch on the left-hand needle.
