Origami 7 - Envelope (re-made video)

I've decided to remake my Origami 7 - Envelope video without any pre-folds and filmed from an overhead view. The instructions should be much clearer now.No gluing or cutting required! :)Materials: 1 sheet of 8.5 x 11'' paper (letter-sized)I'm not sure who designed it, but I got it from a Chinese Origami Envelope book from Pacific Mall.
