This is crocheted in Cleckheaton's Fiddle-de-dee which is a 100% cotton yarn although I can't find any details about it anywhere so I think it's discontinued. It makes up so quickly. This blanket was just crochet in half trebble al the way with a double crochet border, very simple but I think the yarn does the work. I have about 4 balls left over to make something else with - maybe some wash cloths? Not sure.
