Whenever I have corners cut off and they are 1 1/2 or bigger- flying geese, snowballs-I sew the pieces together making HSTs.
If I have a lots left from from a project I work them into a small partial border,I have also pieced them to be Seminole type strips for border or do something on the backing. I used a Holly Taylor print line for Snowballs then put partial borders and checkerboard borders really turned out great. Try doing that-Hope it helps for an idea
