Summary
This summer stole (サマーストール) uses three different yarns. First, with the smaller hook, loosely crochet a mesh with Fine Panaché. Second, with the larger hook, make a series of crochet chains up the length of the scarf, alternating between Scubidu and Farfalla yarns. Add a Scubidu fringe, and then you’re all set for a casual yet expressive look.
