Her double diagonal shift vase is truly creative, which makes me scratch my head to find out how it is done.

To answer the earlier question about paper/folding techniques, I also use Elephant Hide. It's the right combination of 1) stiff but not too thick and 2) easy to wet-fold.

Dianne Stephens To provide sufficient rigidity, use thicker paper like 110 gsm Elephanthide. In Mitani's models, the couplets or flanges are exposed on the outside. It is possible to have the couplets hidden by having them on the other side. For couplets, with two intrinsic straight creases, crimp the couplet at the vertex (point where the polygons meet). For couplets with an intrinsic curved and a straight crease, theoretically, you will have to have an infinite number of crimps on the couplet. Try transforming the intrinsic curved crease into a finite number of straight lines and crimp. This area of 3-D folding is intriguing. We can extend the couplet folding technique to non-rotational symmetric models.

Re: [Origami] Let's Fold some 3D Origami!
There's an overlap of paper on both sides of the intrinsic straight crease, which is curved in the final model. Robert Lang calls the couplets flanges in his flanged pots. We can, of course, have two intrinsic straight creases for the couplet. The surface of the model will then be polyhedral. Cheng Chit What is the best paper to use? Warps can be a problem.

Section 5 Radial Formed Rotational Symmetric Model of my paper "Simulation of Nonzero Gaussian Curvature in Curved-Crease Couplets" published in Origami^5 has reference to Jun Mitani's three-dimensional curved origami. Such models are formed by couplets. A couplet consists of an intrinsic straight and an intrinsic curved crease. There's an overlap of paper on both sides of the intrinsic straight crease, which is curved in the final model. Robert Lang calls the couplets flanges in his flanged pots. We can, of course, have two intrinsic straight creases for the couplet. The surface of the model will then be polyhedral. Cheng Chit

Also I'd like to know if anyone had experience with these type of models or maybe used accompanied this software in his own design. As with much of the fine art generated today, it is to the point we identify new Origami models by the software that was used to design the model...and the the hardware to score/fold it! :-) Personally, I enjoy keeping old school HI alive.
[Origami] Let's Fold some 3D Origami!
Hi Everyone, Recently I have photographed and uploaded some 3D Origami Models on my flickr. I folded them using Prof. Jun Mitani's Software, Ori-Revo. The folding process is quite fun and not so complex, yet the Result is spectacular and amazing. Much of the skills I have in folding from Crease Patterns also come from my experiences with folding these models. They are fun to fold and you can make even simply design your own models. As I felt that this type of Origami is (a bit?) overlooked I decided to come here and share the pictures with you guys and encourage you to try and enjoy folding these models. Also I'd like to know if anyone had experience with these type of models or maybe used accompanied this software in his own design. Prof. Mitani's two books, 'Spherical Origami' and '3D Magic Origami' also gives you insight and more step by step photographed instruction for folding this type of Origami. He also explained the Mathematical and technical aspects of his design method in his paper which presented in 5OSME: http://mitani.cs.tsukuba.ac.jp/dl/CAD_2009_3d_origami_based_on_rotational_sweep_mitani.pdf Here is my Flickr : http://www.flickr.com/photos/emis77/ Enjoy! - Ali B.
