My Dear, Stop when you want or when your tired of it! You have such a lovely blend of colors! They are so soft and light with a few others to just pop! well balanced. I find that crumb quilts really don't make much of a dent in my scrap bin. I tried going about it in a different way. As I make a quilt and create scraps, I turn the scraps into blocks immediately. Benefits.... the colors play nicely together and they scraps never go into the scrap bin! Ta-Da a win!
