Now this is a fun project!
The Geometric Reflections Cowl by Michael Harrigan calls for 1 skein of each of 4 colors of 220 Fingering, a soft wool that's perfect for colorwork and at a great price. Just beautiful!
It's knit in the round on size US 3 needles.
Can't wait to cast on? You can snag the pattern here and the yarn here.
