Here is the second consequence of the Tomoko Twist Tournament.

The twist is obvious this time; it is on the walls, both inside and out.

This model could really do with some good diagrams, step fold photos or a video. Perhaps I will get around to it soon. Perhaps not. There are so many other things to do - like more folding.

There are two crease patterns. The first one is sufficient for many types of paper, the second one adds extra creases which made the side walls cave in slightly instead of bowing outwards. With some types of paper this is a problem.

Once you have made the creases you will probably have some trouble getting the model together. It has to be eased up as it wants to fly open until it has been folded for a few hours and the creases "set".

The key to the whole thing is to work from the Y shaped mountain folds on opposite sides and the diagonals on the other two sides. To begin with, fold the forks of the Y only. This will produce a piece which stands up above the top of the walls. This will become the roof and handle. The stem of the Y is only folded down and across the top of the box after the four side flaps have been folded under around the box and secured. So fold them first. I use hair pins to keep the folded over side tabs from unfolding until I compete the model.

Explaining how to make the "handle" at the top is a little hard to explain in words, but I will try.

It is achieved by sliding the top triangle shaped pieces together with the pointed flaps going under the opposite piece. Then the triangles are folded down on either side. The valley crease at its base is lifted in order to do this and then pushed down again to form the handle.

The result is a lid which is not as firm as it would be if a flap from one side were folded over and into a pocket on the other side. For most purposes it is quite firm enough. The pieces want to fly upwards far more than they want to push out. If you look carefully at the photo you will see that the center of the tucked under triangle on the handle is not quite flush with the flap it is tucked under. I don't think it spoils the look of the handle too much.

I am sure that sounds like esoteric mud! Trying to explain a 3D process in words is very difficult. Be assured that I will diagram this, and a truck-load of other models on this site, just as soon as I can find time between design flights. One day I might finish the origami book I started over a year ago. If I could just stop having folding ideas that I cannot leave alone .......


I am in the process of planning another trip to Mexico in August, September, October. I expect to spend most of my time in various places in Jalisco State, including Guadalajara. I would be happy to visit any folder or folding group within reasonable distance of this area. If you want to issue an invitation please leave a message here and I will reply off site.

And for my Spanish-speaking friends, permítame practicar mi español.

Estoy planeando un viaje a Mexico después de que el año escolar comienza de nuevo. Espero estar en varios lugares en Jalisco, incluida Guadalajara. Yo sería feliz de visitar cualquier grupo papiroflexia o persona en este ámbito. Por favor, deje un mensaje aquí y yo la respuesta fuera de sitio.
