Knit bumpy cowl; knitting needles and acrylic yarn
  • Yarn: Worsted weight
  • Needles: Size 7 DPNs

Note: For this project, you will need about 2 skeins total of yarn. The cowl pictured used less than half of a 218-yard skein of 3 different colors.

This project was made using Knit Pick's Brava Worsted yarn in the colors Mint, Sky Blue, and Lady Slipper (purple).


Size note: This cowl has a structured but slightly loose fit. If you'd like to make your tube more snug, CO 88 stitches.

Project idea: Since this cowl design has 6 "bumps", it would lend itself well to a rainbow version!
