At one of the quilt guild meetings, I won a packet of 5 inch squares.  I generally don't buy anything smaller than fat quarters.  I was puzzled what to do with them.  The colors were very bright and fun.  I looked through my stash and found plain colors that matched the blocks and made little fans.  I used a rainbow rickrack on the curves and a piano key border from the solids.  It hasn't been quilted yet, but it turned out nice. I showed it off at the next quilt guild meeting. I bought enough of the rainbow rick rack to use in the binding, too.
