It doesn't matter that the fabric is narrower. It's white kona and I bought a bolt and just cut 1 yard off until I could see what I needed. It's going much better today. I have 1 whole block together and I've been cutting and getting the smaller blocks put together. The finsihed block is 12 1/2 inches and I have 9 squares to do to finish 1 block. I'm doing card tricks.
