Have you seen Cat Bordhi's new book on socks? I love this book. I love all her books - they are just my pot of tea. The patterns are based on the technique she first introduced with the Houdini sock for Twist Collective. You knit the foot as a seamless piece and then open a space for the leg. I've made one template for my son and plan on sketching everyone's footprint. Knitters' Review has a review here.
