Made from the leftovers of the Tango DK used on the t-shirt; this yarn has lots of mileage. My first try had to be frogged entirely; it was huge! I learned to trust my gauge and measuring. I did a crochet trim around the neck and armholes: single crochet around, then double crochet, chain 1, double crochet around, fudging where necessary to make it lie flat. The bottom half has air-conditioning; I did *K8, K2tog, yo* all the way around, lining it up with the Single Eyelet Rib (BW 1:46) on the bottom of the tank.
