I bought this bag of already cut pieces in two fabrics. One is cut into diamonds and is lilac fabric and the other fabric is a lavendar fabric and it is cut into 31/2 triangles and 41/2 triangles. I have no idea what she cut them for but I have lots of other purples to add to them and I have about 100 of each shape. I hope someone has some idea of a pattern that could work. The diamond is one like you would use in a windmill block. Thanks for any ideas.
