I am making a T shirt Rag quilt for my DGS graduation and have little quilting experience. I have the shirts ready and also did some pictures. His school colors are Maroon and Silver. Most of the shirts are gray, so I did black sashing and I'm thinking a marbled maroon back. I want to make it a rag quilt, so my first question is I saw several posts saying use flannel, but will regular cotton fabric rag OK? Next I like the rag look for the back, but not the edges. I know there are no rules, but will it look ok if I put binding on a rag quilt, I'm thinking of using the same maroon as the back. Opinions? Also, am I right that the seams for the rag should be 1/2 " ?
