Scrap quilts to me are made up of left overs and scrappy quilts are made up of maybe good sized pieces that just aren't planned where they are going to go. A planned scrappy has something about it that pulls it together.
The tumbler quilt is, to me, a true scrap quilt. Even some of the blocks are made up of scraps. It's the quilt that gets pulled out when we sit out on the patio on a cool night. One of my favourites.
The batik quilt is a scrappy in that I didn't plan where any of the fabrics went. I had all the cut pieces in a bag and they just got sewn onto whatever piece was pulled out next. My sister claimed that one.
The star quilt is a planned scrappy to me, because each star has turquoise triangles that help pull the whole thing together.
