You may be able to use it for a Stack and Whack. The best way to tell is to take 2 small mirrors and place them in a V shape and stand them up on the fabric. Then you can see what the colidescope will look like. I did this when I worked at the LQS. It really helped chose fabrics for Stack and Whack. This fabric would have only 2 colors but I see lots of potential for some beautiful blocks.
