Pick your pattern paper that you want to piece together on the final image - stamp the image on those papers also.
Cut out the pieces from your pattern paper that you want to use - The bottom piece will be covered up, so you don't have to cut all the little pieces off of that.
You can also choose to paper piece an embellishment that you don't stamp. You can paper piece your own creation on your page (cars, flowers, owls, etc). I personally like how precise you can be with a stamp, but that's me!
Can't wait to see all your paper pieced creations!
