Norma Bogan's Sock Knitting DVD Filmed in the early 1980s, the Norma Bogan Instructional DVD was designed to assist beginning sock knitters with the operation of their newly acquired sock machines. Although manufactured for use with the Harmony Auto Knitter, hundreds of novices and experienced sock knitters have learned a wealth of information from Norma Bogan's simple style, up close demonstrations and detailed instructions. The entire process of knitting a fully-ribbed sock is demonstrated from start to finish. Norma Bogan begins with the elementary technique of casting on and ends with closing the toe of the newly knit sock with the kitchener stitch. Owners of sock machines all over the world will continue to find this classic, instructional DVD on the art of sock machine knitting helpful for years to come.
