I recently saw in the Docraft "Creativity" magazine the technique of Pyramage. Now this can be as complicated or as simple as you'd like. Mine is probably the simplest form there is.
For my card I started off with 3 ovals (Spellbinders Classic Ovals Small). I used the three middle sizes and cut a white oval with each. I stamped bits of the butterfly around the edges and in the top oval, I stamped most of the image complete. It doesn't matter that it goes off-edge since a dimensional butterfly is going to go on top:
Here's the assembled card (using 3D dots for all layers except the dimensional butterfly which is just glued with some normal liquid glue on the body).
