I've never heard the term "crumbs" before. After reading for a while, I realized I have lots of them, mostly pieces from trimming half-square triangles. Toddlers love the play with them. My one grand-niece throws them up over her head to watch them fall around her. Pure enjoyment. She even puts them back in their containers. I have about 8 but don't always give them all to her at once. Maybe I'll make a quilt out of them for her. Glad I joined this site. I am learning continusly.
