Hello! I knit some plain socks out of my handspun (Sheep 2 Shoe kit in Basan) with a special heel. It's Cat Bordhi's Sweet Tomato Heel. Very simple and VERY smoooooth. You should try it! And, they are the same size but don't look that way in the photo (The "little" sock didn't get quality blocking time because I could only find 1 blocker, needed to take a photo while the sun was up, and had to do it when my son was distracted. Yep!). I will be keeping these cheerful socks for the next cold and sunless day I encounter(You know, 5 or 6 months from now). I love them.
