I use my scraps to make not just scrappy quilts but also rag quilts.
For scrappy I just sew everything together and than square it off to how big I want it to be.
For rag quilts I'll sew squares, retangle, strips and such together than cut them into rag squares or rectangles, stars, hearts, flowers, etc and create one of a kind rag quilt. I have one right now that I had purchased fabrics purposely to experiment with using five or six different ones and cutting some of it into 1 1/2, 2 1/2, 3 1/4 inch strips sewing them together and than cutting it into a rag square. I'm mixing these up with sized squares of various colors I used to intermix them in the lap quilt. For the back I'm using an explosive colored material for back rag square so they will all be the same.
My next step is to sew each rag block in free motion quilting instead of doing the traditional X across it, then I will sew it all together.
