Is anything goes.
I've been creating with the SSS September card kit and creating different looks from the same kit.
Here's a couple more cards I made from the kit.
I created the above card using a few bits of paper that are included in the kit, a piece of cs from the kit and one of the sentiment stamps. I really live the way that this turned out. It's given me the idea of what to do with paper scraps now :)
This second card is just simply stamping. All the stamps used are from the kit.
