Just some handy info on charm packs that I picked up somewhere, I think it was Missouri Star:
1 charm pack = baby quilt 36x54 inches
2 charm packs = crib quilt 45x60 inches
3 charm packs = lap quilt (sorry I don't have the size)
5 charm packs = twin quilt 63x87 inches
8 charm packs = queen quilt 84x92 inches
