Join knitwear designer and instructor Annie Modesitt on this Interweave Knits workshop video for knitting double. Most commonly considered the act of using two sets of needles to produce double-thick knitted fabric when stitches are joined, double knitting can also be achieved by knitting two pieces on one set of needles simultaneously. With Annie's help, knitters of all skill levels can learn various types of double knitting with step-by-step instructions and visuals.
