This shell cowl is crocheted with five different colors of yarn, conveniently chosen by Caron X Pantone. I used to colorway Tree Rings with a size J hook. You can choose your own ombre or color blocked color scheme if you wish. This cowl crochets up quickly, and is just a one row repeat, changing colors every four rows. This is worked up in joined rounds. My finished cowl is 15” high and 30” around.
