Lately I made a pieced border of pinwheels made from the triangles I trimmed off of the snowball blocks in the body of the quilt. I did not have enough pinwheels to go all the way around, so I divided them between opposite corners, then I finished the rest of the length of each side with a matching fabric border. I've noticed other quilts done this way too, so I hope the quilt police do not come after me. I've decided that it is a great way to go with pieced borders. It doesn't have to come out even and I can just trim to fit at the non-pieced end.
