I've used the Apple Prints dies and coordinating stamp set, along with Teach & Inspire stamp set. You'll want to work with some dies that have a coordinating stamp set to go along with it, so you can stamp the shape into the cut out and make the shaped edges look seamless.
During the last monthly release, I made a card with this technique using Life Is Beautiful stamps and dies, you can see that one here, just to get more ideas of what you can do with this fun technique. I hope you have fun with it! Join us in this challenge, and you might win a $25 gift card!
