As Live2teach said there have been many posts about rag quilts. I made my squares 7" with a 1/2 inch seam. I used cotton for front and back and flannel for the middle. I cut all three squares the same size. It really does go together fast and easy. The hardest part about a rag quilt is snipping it after it is sewn. I really suggest that you buy a pair of fiskars rag quilt snips. It will really save on your hands. I have made three and am working on my fourth. They are going to be Christmas presents for some of my close friends and family.
