We have an Accuquilt Studio at the store, and the die we use most is the 7" tumbler with 4 tumblers on the board. We can cut up any line of fabric into a tumbler kit, and they sell really well. Tumblers are so easy to sew together! People love them! We also have a 4" tumbler with 6 tumblers on the board that is great for baby quilts. Customers come to the store to use the tumblers for cutting up their older fabric to use in charity quilts.
