I am loving the Preserves cartridge right now, especially since I have My Pink Stamper's Fruit & Veggie Puns stamps :-)
I cut the big watermelon at 2 1/2 inches and the smaller watermelon at 1 1/2 inches. There are 4 layers for these and it makes it so easy to put together! The stamp is a MPS stamp and then I just used cardstock, some self-stick gems and stickles. This went together so quickly!
