You can change the style by using a different ribbing pattern for the leg. After you make a few pairs, you’ll memorize the basic structure and techniques of sock making, and you should be able to add or remove stitches to adapt the basic pattern for using stitch patterns with different repeats. It’s really easy to make a sock, but the instructions look confusing. The only way to figure it out is to make one. If you don’t want to make a pair as a test, use extra bulky yarn and fat needles and knit a Christmas stocking.
