The novel will appeal to fantasy fans, even if they do not knit. But I am fully aware of all those knitting and spinning clubs that revolve around Lord of the Rings, Doctor Who, and Harry Potter. Knitters seem to love fantasy, and what a great idea to create a fantasy book with built in patterns.
Look at those needles! Magical needles like that would never let you drop a stitch or miss an increase. Wouldn't it be something if there were a knitting needle shop similar to the wand shop in Harry Potter? A pair of needles meant only for you?
I have never thought to knit a cape, but doesn't it look fabulous?
A good fantasy story (with a map!) and inspired knitting patterns to keep the story going. A knitters dream come true.
