I have 26 pieces of clothing and 3 blankets I can use. She wants it either double size or queen size and said I can add borders if it helps, (which I'm sure I will have to in order to reach the size I need.) I would like to keep the clothes in their original shape and just cut the backs off. So, my squares will have to be at least 12". I am just looking for something that I can plug in sizes to a grid before I cut anything.
