I folded this last year, so I don’t remember if this is the one I designed, or if it is one that I folded from instructions I found somewhere… There are a good number of origami Jack-o-Lantern models with instructions available on-line, although most of them are not great IMHO. I am still trying to find the directions I used to have for a relatively simple version made from two pieces of paper, which I used to fold a lot a couple of decades ago. The problem is, I have more than a hundred origami books and magazines, and it could be in any of them… or in some other publication I no longer own…
