I altered a free template that I found on the web so it wouldn't waste so much paper. If you cut the file twice, it makes 2 trees. There is a square template to use for the fold lines on the bottom (glue one over the other crosswise), and a triangle template for the decorative papers to add on each side. No score lines on the svg, because it's self explanatory (point of the tree to the corner of the square). I glued 2 of the branches to each other on 2 of the sides and left the other 2 free for opening the box. Punch holes in the front and back tree to run a string through for closing the box and as a hanger. Filled them with my favorite Hershey kisses.
