Very cute caps! I have been wanting to crochet or knit myself a little sleeved shrug for sitting in the air conditioning. I saw someone wearing one that was done in garter stitch. It was simply a rectangle of knitting that they had sewed both ends into a sleeve shape and left the back part flat. The garter stitch had enough stretch so that the back fit across the neck and shoulders perfectly and the little sleeves were about elbow length. It was done in a soft fluffy yarn.
