Ten-Sided Yin-Yang Globe

This is a ten-sided yin-yang globe, a modular kirigami model I designed for a friend to use in a gift exchange for the 10th Gathering for Gardner. Martin Gardner wrote the Mathematical Games section in Scientific American magazine for many years and had a big influence on a lot of folks, paperfolders not excepted. My […]

We’re back from the Convention in New York and our head is still spinning a bit, but not so’s you’d notice. We can report that a good time was had by all and that Mélisande*‘s and my class on Monday went very well, indeed. Tato boxes were the topic of the day and it was […]

But this lacks…authenticity. I’m way big on authenticity. The method for making a decagon from a square is not […]

Puff Star, Redux

A Mister Richard Feder of Fort Lee, New Jersey writes in to say, “Hey, what’s the deal with the Puff Stars? How do I fold a Puff Star? Does CP stand for something? How will I know if I have folded a Puff Star or something else? What’s a perf strip? Will folding Puff Stars […]

Puff Star

This fold took its inspiration from the little puffed stars we used to make by tying overhand knots in perf strips. (Remember perf strips?) Also, one night, I got to wondering, what happens if you make a bird base from a pentagon? As it turned out, the model was much cooler when made from a […]
