Quilters use a scrap of fabric to start sewing so nothing goes down the throat plate of the machine. I've been using the scraps that way starting with a 2" center and doing Log Cabin blocks. It's amazing how fast you end up with blocks. Each stack has at least a dozen blocks. The random piecing of the strips adds to the design. These just have the 1" then the 1 1/2" strips on them.
I love using up bits and pieces to come up with something but somehow the stack of strips never goes down.
