I used the technique that I've seen on SCS where you add colour to the debossed side of the embossing folder and then stamp an image on it. Then put your cs into the folder and run it through the Cuttlebug or Big Shot.
I added a snowy bank, two die cut deer, and a die cut sentiment.
And a totally different tree:
I used Loll Thompson's alcohol ink smooshing technique with various green alcohol inks and Yupo. See her video here (go to the 2:20 minute point). Loll uses glossy cs, but the technique is the same with Yupo.
I had a negative left from a Tim Holtz Christmas tree die cut so layered it over the Yupo. I stencilled some snowflakes around the tree and added the sentiment "O Christmas Tree". It's popped up on fun foam for dimension.
