How do you fix a dropped stitch on a finished piece?
Picking up a dropped stitch in your knitting is easy enough when the piece is on your needles. You simply hook it up, and slide the live stitch back onto your needle.
Can you fix a dropped stitch after binding off?
Wrap the yarn back over the top of the dropped stitch and weave it in and out through the stitches on the back of the piece. This tacks down the dropped stitch and keeps it from unraveling again.
