This cowl pattern is knit in the round on US size 10 (6mm) DPNs.
Chunkier or finer yarn can easily be substituted but you would need to adjust your stitch count up or down accordingly.
The icord edging gives the pattern a lovely finish, for more adventurous knitters. The finished cowl measures approximately 5 ½ x 10 inches and should fit a child from 2-10 years
