This is an older post on Moda Bake Shop, but I wanted to share the link to this pattern as my son and I were looking for an easy pattern that used one layer cake. (There is an option to use more fabric too, but we stuck with the one layer cake). We made him a quilt top using ONLY the layer cake and there was *maybe*1-2 inches of waste from the whole thing. I love the "boxed" in look. This pattern is pretty easy, even my 7 year old worked on it! Hope you enjoy. :)
