We have a woman who collects these at Stashbusters (a yahoo group) and makes them into beautiful quilts, she can combine things we never think of. Then she donates them to Des Moines area charities.
I like the idea also of making them in a colorway that can be used a lot...your favorites, or all fall colors, or all pastels...
I have framed beautiful blocks in glass frames that have no outside edge so the block is the feature.
