They both use Stampin' Up Double Sided Designer paper (Bella Rose) and one uses Kiwi Kiss and the other Pink Pirouette. I used my Coluzzle to cut the oval in the designer paper and then created my tree and adhered to the front of the card. I also used a brad on one and a Rhinestone brad on the other.
They are quite fun to make once you have tried a few so give it a try! The card base is 5 1/2" x 8 1/2" and then folded in half. The designer paper is 4" x 5 1/4" and I used the 3rd ring on the Coluzzle to cut out the oval). The dimensions for the four pieces of designer paper for the tree are 3" x 3", 2 1/2" x 2 1/2", 2" x 2" and 1 1/2" x 1 1/2". Folding each square as follows: Fold square in half, open back up. Fold in half the other way, open back up. Fold corner to corner on the diagonal, open back up. Fold the other corner to corner on the diagonal, open back up. Now fold in the sides so you have what looks like a triangle. Fold left and right sides of the triangle in towards the middle. Repeat with each of the other squares. Stack on top of each other to form the tree.
