Vertebral Stretch

Vertebral Stretch – 3D Wigglies

I’ve been experimenting with this three dimensional folded structure for a little while now, and for reference I’ve created a simple crease pattern in case anyone wants to fold this. You can grab one of two versions – one on a grid, and one without. They are much smaller versions meant for reference understanding; just expand the construct to make it larger. The version superimposed on a grid: (sorry for the misalignment, this was done for reference purposes only, not for publication anywhere!) I hope you enjoy, and if you fold one of these please send me a photo! I’d love to see how it turns out.

Tessellation primer booklet

Tessellation Basics booklet now available – free PDF!

Well, I had all the best intentions to add more content to this booklet – but it’s hard for me not to just put in all the material from my book! So I’m posting it now in the same format that I used at the Origami USA convention this summer. Download the PDF This document is just a small taste of the material from the book, put together from some of the draft work and preliminary writings. The final product is quite lengthier and more detailed, as well as more polished. (Editors are very good at taking text like mine and making it readable!) This 8 page booklet is meant to be printed on 11×17 (or A3, in a pinch) double-sided- so it can be folded into a proper booklet shape. I had a lot of fun putting this together- thanks again to Jamie and Jeff for helping me to create and format this document!

star twist version 2.1, backlit

Star Twist 2.1

Francesco Decio taught this model of mine at the Italian CDO convention in Verbania, in December 2006. I was really impressed to see that he had made some great instructions, much much better than the confusing CP that I made a while back. I’m really thankful that he created these wonderful instructions, and furthermore that he has shared them with me and allowed me to share them with you.

Joel Cooper's Basket Weave, CP

Joel Cooper’s Basket Weave, Crease pattern

This is a crease pattern for Joel Cooper’s “Basket Weave” design, which features so prominently in many of his tessellation designs. It may have other origins as well- Joel has said as much; however, I have only seen it in his work, and that’s the first place I saw this, so until I see otherwise I’m crediting him with the design. That being said, here’s two different CP’s for it: one without a grid, and one with a grid. I highly recommend looking at the grid version to understand the spacing for this design, as it’s rather tightly packed together when folded.

If you are so inclined, I uploaded two different crease patterns for this design: Waterbomb/Flagstone Tessellation, crease pattern (with grid) Waterbomb/Flagstone Tessellation, crease pattern (no grid, as pictured above) I’m really at somewhat of a loss on what to name these tessellations. If folded fully they become flagstone tessellations, ala Joel Cooper; if left three-dimensional, they are “waterbomb” style tessellations (although waterbomb is the wrong term for us to use here, but we’ll dispense with that argument for the moment.) Regardless, this is a tessellation- the old standard, triangles and hexagons together. When you fold “normal” tessellations, the twists are always the dual of the tessellation you are folding. (For example, the tessellation has a dual made up of rhombic stars- and the rhombic star tessellation, when folded, has hexagon and triangle twists, which most people actually think of as a tessellation even though it’s really the dual of that…) However, with these “waterbomb” tessellations, there seems to be a little bit of change due to the geometry involved. I …
