The Carpenters Star is very simple, just squares and triangles. Also, for the basic shape is only 8x8 square (64 blocks). You can decide on the size of each block, 3 inch blocks will be 24 in X 24 in square, up to as large as you want. Its very simple, I did the cutting in a 1 to 2 hrs, and the sewing was actually 3 to 4 hours. A real weekend quilt!
I have a couple of websites on my post that gives instructions, and another one to help with the lay-out. It made it very simple.
