Wiggle is a boomerang style scarf that can be as small as a bandana and as large as a full size shawl. Use any yarn that works well for lace knitting. The pattern includes details for a scarf made from fingering, dk, and worsted weight yarns, but you can knit with any gauge to any size that you like.
The lace is freeform, so there are no charts or written-out patterns! Instead, there are guidelines for knitting freeform lace so that your project is one of a kind.
