Origami iris

"My name is Emily, I’m going to show you how to build an origami iris. First, fold in half. Once more. Make sure the open end is on this side, and bring this point to the bottom corner and fold this line outward- make a square. Do the same thing. Take this corner, match it with this one. Make sure this become a mountain fold, like so- making a square. Make the open points face away from you. Take the corner, make another mountain fold on the center line. Flatten. Do the same for all four edges. Take each corner and fold towards the center. Now for each side that you folded inward, you’re going to open and pull, like so. Next side. And fold each side upwards. Fold in half to the blank side. Crease like so. Do the same for all four unfolded sides. And the last one. Open each side to the blank unfolded side, take the corner, and fold to the inner crease. Repeat on all the sides. Take the open end, fold down to where it stops. Repeat on the opposite side. Open like this. Do the same. And that is the last step in the origami iris."
