IMO, I make 2 types of scrap quilts. Both are using left over fabric. The 1st is using scraps from my scraps, not paying too much attention to placement. The 2nd type is a controlled scrappy where I pick certain colors from my scraps to make a quilt. My scraps are either scrapes I have from my previous projects, or scraps I have either swapped to get or someone has given me. I consider my scraps different from my stash. My stash is new fabric I have bought but not used yet. So I would not consider a quilt using my stash as a scrappy quilt, even though it looks scrappy.
