On "Stamp something" there is a challenge about using your favorite papers or colours. I've used one of my favorite stamps which is made by Evy for "Minnehjørnet" (a norwegian scrap shop) http://minnehjornet.blogspot.com/. I've used a big tag underneath the stamp and the tag is ending (or maybe starting?) on the back of the card. The christmas trees is from one of my favorite papers, 3ndy papir" (http://3ndypapir.blogspot.com/) - also a norwegain design. I just cut them out from the paper. My favorite colour is blue and i feel blue is one of the main colours in my card.
A really funny challenge - you can join to!
