Have you ever been that close to finishing a sock but had to spend an hour hunting up your instructions for the kitchner stitch? Or puzzled over the terminology--which is the instep and which is the foot? The Sock Doctor is a handy reminder of all the things you need to keep your sock knitting on track. One side has the parts of the sock labeled, so you'll never confuse the gusset with the flap again. The other side includes the instructions for the kitchener stitch so that you can close the toe and finish that sock! Best of all, a darning needle is stored inside the Sock Doctor, so when you are ready to kitchener, you have what you need. The Sock Doctor comes with a built-in clip so it can be hung from the handle of your knitting bag.
