Here's a super simple card I made.
The image is from Hero Arts and it's called Winter Trees. I stamped it and then did a little sponging on the lower hill for a bit more dimension.
I cut a window in the card front and mounted my image behind it.
I framed the image with some Diamond Stickles.
The sentiment came from Stampin' Up's Polar Party.
As quick and simple as this was, I still think it has a stunning effect.
