I decided a while ago to make a bunch of dishcloths and sew them together to make a blanket. I have yet to do it but a lot of people on here suggested that i make them all in strips instead to avoid seeming. When i finally do get around to doing it i will certainly do it that way. Your blanket is beautiful. If you are looking for more ideas for squares then go to www.knittingpatterncentral.com
