If you have that many you could make a one patch charm quilt. I'm collecting squares to one day do this. :lol: one day is probably a long way off but whose counting. In a traditional charm quilt 1000 different pieces were used no two the same, but no one has to stick to rules. some ideas for a one patch could be Pyrimids or Tumbler are reasonably simple to piece, Dutch Tile is another nice one also Kite. Apple Core is a really nice one but is a bit trickier as it is a curved one patch. Hope that's some help :D
Here is a link to templates for one patch charm quilts
