This is the perfect project to use up those many small odds and ends of sock yarn you have collected over the years. Or a perfect excuse for buying multiple mini-skeins of fingering weight yarn!
This project is designed as a cowl, starting with a provisional cast-on and knit in the round so you can graft the beginning stitches to the end stitches to make a perfect tube. You could also make a scarf, binding off each end separately.
The cowl takes 1300 yards in Color A and 1300 yards in Color B. The cowl shown used 650 grams of left over sock and fingering weight wool and wool blend yarn in many, many different colors.
A suggested substitute yarn is shown below.
