In this Arts & Crafts video tutorial you will learn how to Origami a paper envelope without glue or tape. Take a piece of paper and fold it in half hamburger style. Fold the open edge of the top sheet of paper back on itself so it reaches the closed edge. Repeat this step again. Give it a good crease, open it up and fold the open edge back to the middle crease and fold it back along the middle crease. This becomes the bar of the bar envelope. Now fold the other open edge of the paper so that it reaches the bottom of the bar. Give it a good crease and open it up. You will then have to watch the video for further steps as it will get confusing without the demonstration.
