I made this card from Martha's pattern. I like the way it turned out. I used a sturdy white paper with some swirlies on it that remind me of snow. This was actually my second attempt. I misunderstood the directions the first time around and cut my card completely in half the wrong way.
The card lays perfectly flat for mailing and the branches sort of pop out when the card is bent.
If you want to do this make sure you have a sharp xacto knife. It will make all the difference in the world.
