"With and Without Collage" is the name of this technique from the current Technique Junkies newsletter. It's been awhile since I've played with the TJ techniques, and I think I might have inadvertently "modified" this one. The tech calls for smooth cardstock, so I just flipped a piece of textured cardstock. It's still not totally smooth.
The image is from Hampton Art Stamps, and I'm working hard to use my un-inked rubber before I go back to the "old faithfuls" in my collection.
