Here's a design that was inspired by Carol G's tree quilt in our online galleries. And you can stitch it two ways, as a rag quilt or as a non-rag miniature. The rag quilt doesn't have huge units -- they finish at 4" square. The mini's smaller of course, with each square in the quilt finishing at 2-1/2". You'll find a couple of layout and assembly options, so be sure to read through the pattern before you begin.
