Nothing really fits the category of this like 'stickers'. I started with striped and script background to make the card look like a room. Then I used three vinyl tree stickers to create a layered Christmas tree and decorated it liberally with star stickers.
The image is from the stamp catalog, colored with Copic markers, and the text is a rub-on. I haven't decided if this image is supposed to be the 'steadfast tin soldier' or a 'nutcracker', though.
