A Simpler Way

Frangipani Box, Variation 5

I have this longish post about the evils of encroaching copyright, but it keeps boring me to death and I still haven’t finished it. So, while we’re all waiting for that little gem of wisdom to roll off the presses, why not take a whack at a simpler version of the Frangipani Box? This is a version I’m working up for teaching at conventions later this year. (Did I mention I’m going to Verbania in December?)

How is it simpler? Well, I like to think that the folding sequence is more, you know, sequential. You start with a pentagon in a circle, always a good place to start. Then you carefully examine the crease pattern. (Postscript.) There are a variety of ghost lines floating around here that will help you find the answers you will need to complete the model.

  • Where do the five curves around the edges come from?
  • How do we make the pentagon for the bottom of the box?
  • How do we know where the mountain fold on the side of the box crosses the curved fold?
  • How do we know where the mountain fold on the top of the box crosses the mid line?

And you may be saying, “What’s so simple about that?” Not simple, my dear chap, simpler.

You may also be saying, “Do the mountain folds on the side of the box really need to be curved?” And the answer is, maybe not so much. Here’s a crease pattern (Postscript) where the folds are straight. The difference in the finished model is subtle. I prefer the curved version.

Big howdy to our readers in Taiwan. What’s happening?

    Are you taking a ship or do you plan to paddle all the way there?

    Ooh, what’s French for chagrin?

    But a fair question and one that my wife asked when I told her about the invitation. I have little faith in sedatives, so am investigating hypnosis.

    Oh, come one, it won’t be that bad. Ingesting large doses of alcoholic beverages might help, but remember, once you land, that’s when you get really drunk ;P
