I make quilts for QOV (Quilts of Valor)there are several online groups that do mystery QOV quilts which are really fun. Smallest size that QOV will accept is 55x65 and largest is 72x90. They provide longarmers for those that want to use the service.
Heres one that is a yahoo group:

and then persimmon quilts has a mystery quilt for QOV also.
