I would have one workshop on what to do with scraps that were not the usual ideas, or else ways to use one block by itself, i.e., the background of a clock, a pillow, a kindle cover, toilet seat cover, etc. Making a long strip of 2 1/2" strips about 8 inches wide several feet long from scraps. Then using this to make either borders as you need it or to make bands to finish off pillowcases - the idea being to just keep adding on to the long strip on one end, cutting off from it on the other end as you use it up. Fold it in half for pillowcases, trim as needed for borders.
I would really enjoy an ideas workshop like that.
