Swans Island Patterns - Brooke Cowl is a similar pattern: 20 (5 sts. / inch) finished gauge, scarf garment, for women, and worsted (19-20 sts/4 in) yarn gauge. You make also like Grace Akhrem Patterns - Greenleaf Ascot, which is another similar pattern: scarf garment, for women, worsted (19-20 sts/4 in) yarn gauge, and malabrigo worsted suggested yarn.
You may enjoy taking a look at the Cascade 220 Superwash Split Personality Mitts, Noro Kureyon Phoncible Hat, and Malabrigo Worsted Merino/Lace Howlcat! Cowl (kids) kits all using Dull Roar Patterns.
Hopefully our suggested yarn options for Zam Hat can help you come up with your next exciting new project idea!
