The front layer of hills is popped up on dimensionals. The hills were created with Simon Says Stamp Stitched Hills and Slopes dies, which are pretty much NBUS even though I've had them a while. I think I'll use them more, now.
The trees are varying numbers of layers thick in order to create more sense of depth.
