The Alanya sock pattern designed by Jeanette Sloan features a "Turkish heel" sometimes known as the "afterthought heel" which is worked after the main part of the sock has been completed, allowing it to be replaced as needed if the sock wears out. The pattern uses Artesano Hummingbird 4 ply Alpaca yarn. This yarn is identical in weight to Artesano 4 ply in the solid and melange colours, so the pattern can also be knit with one of those yarns.
