A couple of years ago I saw some pictures and patterns on the internet for this beautiful modular origami swan. The swan was made from about 500 triangular pieces, each folded from small rectangles of paper.

I decided that I wanted to make one, and went looking for a pattern. The pattern I settled on required about 400 triangles. I started folding the pieces, and eventually I got them all made and started assembling the swan, but over time other things took priority. Recently I decided to get that project finished, and I’m happy to say it turned out beautifully.
