This is not a quilt block that you sew. It comes with a plastic frame that has foam rubber in it, with slits cut out in this pattern.You use a tool like a plastic knife to push small pieces of fabric into those little slits. When you're finished, it looks like a sewn quilt block. You can hang them on walls or stand them on shelves. They're easy to make. I didn't buy the tool, I used a plastic knife that came with my grandson's play doh set.
