I recently decorated my wall with an origami pattern. I’ve done another wall design before (and a previous iteration of the butterflies that I never posted).
The butterflies are Akira Yoshizawa’s design (instructions here; many other diagrams and video instructions available online). It’s a fairly simple design but very elegant. I folded about 100 butterflies from squares ranging from 2 inches to 6 inches, and the total pattern is about 3 feet x 6 feet.
Here’s a close-up that shows the individual butterflies more clearly:
