Since I found the tutorial for these cards on Stamping Videos, I can't take the credit for the idea. But I can take the credit for making them suit my personal style.
Hello Retro!
Now because I'm inherently lazy, I made a trip to Michael's and purchased a package of Recollections blank cards & envelopes. The size I used for these cards is 4" x 5-1/2".
For the outer frame of the card, cut a piece of paper into a 5-1/4" x 3-3/4" rectangle. And for the tree you'll need to cut four squares at 3", 2-1/2", 2", and 1-1/2". For my card, the two papers I used are from Anna Griffen and KI Memories.
Next, using my Cuttlebug and a Spellbinders Nestabilities die, I cut an oval into the center of the rectangle. Affix this framework to the front of your card.
Take the 3" square of paper and fold it in half. Open and fold the paper in half again, in the opposite direction.
Open the square up again and this time, fold the paper into a triangle... corner to corner. Open again and repeat the process in the opposite direction.
Now that you have all the creases in place, fold the square in half again and push in the two sides to form a triangle.
Next fold each of the triangle's "wings" down as shown:
This is what you should end up with.
Repeat the same process for the other three squares.
Now it's as simple as using your glue dots and nesting the sections of tree on the front of the card. Top the tree off with brads, bling or buttons. For my card I used a Fancy Pants rub-on.
And you're done! Super easy, huh?
Oh... one more thing. Don't worry about how these cards will mail. As shown below, they'll lay completely flat within the envelope.
