Those might be in some of their books, as blocks in a sampler "crazy" quilt. Just a thought, because I have some of their books with patterns of quilts with various blocks in them. You could also draft up your own blocks to put together in the Buggy Barn way. I have done that with my own unique designs, like a cat and a dog, etc. It's fun to do. You just have to keep small details away from the edges of the design, as they may get cut off in the squaring up process.
