I found this delightful design in The Christmas Origami Kit by Anne Marie Harris. It comes with instructions for six traditional origami designs and twenty four sheets of 5.25" origami paper. The trees can be made in any size by using a smaller or larger square sheet of paper. A 5.25" square folds into a 2.5" tree. I'm using them as holiday ornaments, gift tags and place cards. Make your own with the simple tutorial below. No scissors or tape, a little glue is handy.
