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. Here's a great video showing how this is done: http://www.youtube.com/watch?v=HVeUteBJEsI&list=PLCA62A5AB7F53FB9E&index=12&feature=plpp_video

Tink - or Undo Your Knitting

Sometimes there is no way to "fix" a mistake without "unknitting" your work. Here's a tip to make that task easier: Use a needle a couple of sizes smaller than what you are knitting with. For knit stitches: hold your yarn in back of your work and insert the left (smaller) needle into the stitch below the first stitch on your right needle. For purl stitches: hold your yarn in front of your work, and insert the left needle under the "bar" below the stitch. Pull the yarn out of the stitch.
