This was originally an eBook, but high demand has pushed me to consider printing them as well. The Parallax series of scarves in double-knitting have been an obsession of mine for some time, and the striking op-art visual intrigue combined with the relative simplicity of their execution has made them popular knits for adventurous knitters. There are 5 patterns in this book -- 4 scarves and a simple seatcushion. The first 3 patterns are just standard double-knitting so this is a great way to learn the technique as well!
