I have used very small pieces cut in HST shapes and glued them to note cards to look like quilt blocks so even the smallest things can be used. I am sure someone will want them. Another idea I have tried once was to take the slivers of fabric that are trimmed off when squaring up blocks, sort them by colors (sort of) and then arrange them on a piece of muslin in a nice arrangement. (i.e. blue slivers at top for sky, green slivers at bottom for grass) Then cut out some black silhouette shapes of something you like (cats- horses- flowers houses) and place over the slivers.Place a piece of very fine netting over the whole thing and then randomly sew it all over to hold everything in place. Put a binding on and Voila...you have a wall hanging work of art.
