Help -- How do you fix a hole in your knitting?

I recently completed an Auburn Camp Shirt. I was trying to remove the little “wool balls” that occurred during blocking and my little hand held machine sucked the shirt in and cut the wool. I have one stitch on a pin and a yarn end. I’m wondering if anyone can help me out with how to fix the hole. The shirt is completed so I really don’t want to have to take it apart. Does anyone have any suggestions?

Take some of the yarn and sew them closed. Weave it over the sts that are broken to secure them and thread the ends through the nearby stitches.

What Sue is talking about is also called darning. Use a length of extra yarn to darn it - you can pick up that loop with a stitch and then weave the rest of the yarn in to secure it.
