blueribbontoes is collecting scraps in all colors for an extensive hexagon quilt. Her size is 3/4" to 1"
When I have scraps, I kind of decide by intuition and by how much fabric I have left when all is cut. The less fabric I have left, and the more I like the color, the smaller the scraps.
I have a "scrap bin" - a tall Rubbermaid tub, that all my small odd cuts go in. As I read about people needing a certain color, I rummage through the stash to see if I can share.
