I'm in the process of making some thank you cards and this is one of the sample cards I made.
I simply stamped my image and colored it using my SU markers. The lower half of my background is embossed using my Floral Fantasy cuttlebug embossing folder and I added two ribbon tabs on the left side of my stamped image.
I made another card similar to this one, it can be found on my blog if you would like to see it:
