Here are two versions of a simple crochet scarf using squares as the basis of design. The first is based on 3's ... treble crochet, skip 3 chains, etc., using a light sport yarn by Noro, Silk Garden. That is the multicolored one in the background. The lime green scarf is based on 2's ... double crochet, skip 2 chains to make a square, etc. using Ultra Merino 3Ply, a handdyed Wool2Dye4 yarn. I am liking the more delicate one.
