This origami video shows you how to make an envelope from a rectangular sheet of paper – no tape, glue or staples needed. This is one of my favorite folds. I use it a ton for giving cards (or gift cards)… of course if you use this envelope, you’ll probably need to make a custom card, but that’s simple enough, right?
- 1 rectangular sheet of paper (copy paper, printer paper, office paper, 8.5×11, A4)
— you can use a square sheet of paper, but it will make the envelope much thinner
