I uploaded two crease patterns and some basic info on a star design by Shuzo Fujimoto; here’s my flickr post on the photo shown above. I don’t really know what the title of this piece is; I saw a crease pattern in a book, and some basic illustrations of the finished design. This is my best effort at recreating the crease pattern and folding sequence, which I think comes out to be very close to Fujimoto’s finished design. I have no idea how he handled some of the collapses, so I did them in the method that makes the most sense to me. This design is very similar to the star twist v2 I made a while back; this is actually the layout I had been trying to accomplish when I designed that piece. I knew it could be done, but the method has eluded me- and now I know that Fujimoto folded it back in 1976, two years before I was even born. The folding on this model is really somewhat difficult- I actually …
