Pattern Description from Knitting for Peace: “This hat features a unique construction technique. The body is worked flat, from side to side, with a vertical stripe pattern. Simultaneously, decreases are worked on one end and increases on the other, which gives the hat a parallelogram shape--a rectangle with a slant. When the parallelogram is sewn together, the stripes naturally swirl around the hat.” Finished Measurements: 16 (18)“ hat circumference. Yarn: Main color - Approximately 130 yards 4-ply worsted-weight yarn (MC). Contrast color - Approximately 70 yards 4-ply worsted-weight yarn (CC).
