I was playing around on You Tube and found a video on an Origami star box. My friend Kathy made one that I loved and I had to make one. It took about 5 minutes and is very easy to do. You need a bone folder to make the folds crisp and a square piece of paper. I used a 12x12 sheet of paper and it made a box with a 3 inch opening and 5 inch inside and bottom. Hope you try it.
