How To Rip Back Rows

Use the smallest circular or double point needle that you have, preferably a size 1, 2, or 3 needle. Find the row BELOW your mistake, and pick up the RIGHT loop of each stitch (including edge stitches). Remove your regular knitting needle from the top row of your knitting, and rip back your stitches until you reach the skinny needle row. Start knitting again with your regular needle.
