This little chart is intended as a supplement to the brilliant Hogwarts Double Knitted Bookscarves by the lovely and brilliant Ann Kingstone. Â Her charts are available on Ravelry.com, a free site for fiber crafters. Â I used this chart to make the double-knitted bookscarf you see here. Â It can also be a repeated stranded motif on a hat or socks or sweater yoke, or used singly as intarsia-work, perhaps on the back of a mitten!
