Many years ago these origami trees were my Christmas card. I sent three trees of different sizes. They were made from a kelly green card stock that I decorated with Gel pens.
I love making these tress. They are a fast project, something you can finish the same day you start.
All you need is square piece of paper, size is up to you.
Make on diagonal fold.
Fold each side in--- to meet first fold.
Now fold the bottom upward.
Next unfold slightly, open the back up so it stands up.
I like to use scrapbook card stock.
I add paint or glitter to the paper's printed patterns.
