I too had that problem with my "Day of the Dead" fabric collection. I took a class on making a quilted jacket from a sweatshirt. It's a crazy quilt on a sweatshirt concept. Anyhow, my quilting instructor had us stack the fabrics and just slash cut them. I could not do it, so she made the first cuts for me. It was easy after that....
As you can see from my photo, the end product was shown a our local quilt show.
