You can buy sock wool and sock yarn here needed to make this project here, directly from Artesano yarns
You can also learn to knit socks by visiting the Artesano Academy

These lacy socks are knitted toe up using circular needles and the magic loop method. The Turkish/Eastern cast on method is recommended but Judy’s Magic Cast On and other toe up cast on methods can also be used.

These beautiful lacy socks are inspired by the beautiful beach at Talland Bay in Cornwall.
