I used "what was I thinking" fabrics in a number of ways. I do use them in log cabins or other places where I cut them into small pieces and they work great. If they are larger pieces, I sometimes use them for backing. I just used a "what was I thinking fabric when I needed more orange and pink squares. I just cut 2 1/2" square out of the orange and pink parts of the fabric. Worked great! I've also used those fabrics as base fabrics when I'm doing wearable art. I don't get rid of them because I have so many uses for them!
