Here I'm beginning to sew the first leg. Note: You don't sew on your pen line; you sew on either side of it (thus creating two legs). The width of your machine's presser foot - about 1/4 inch - is just right. As I said, start at the top about an inch or so below the heel. Be sure to back up a little to secure your stitches. (For those in the know, you may want to use a ballpoint needle on your machine if you've got one. Otherwise, don't worry about it.) Sew all the way down til you get to the sock's cuff. Then stop every so often and turn the sock so you round off the foot. You can see this better on the next page. (And yes, I sew over my pins. I'm very naughty.)
