Vespertilio - by Ioana Stoian

Vespertilio – corrugated paper bat

My partner Ioana Stoian recently created this wonderful model of a bat, using origami corrugations – her first origami design! I’m very pleased with this model and helped her to create a simple set of diagrams and a crease pattern, which you can download via her site: You can see it also folds flat – the world’s first “flat pack” bat 🙂  

Polish convention diagrams

I was the guest at the Polish Origami convention a few weeks ago, and I had a fantastic time in KrakĂłw! I heartily recommend to anyone that they should attend this convention; the organizers Krystyna and Wojtek Burczyk did an amazing job putting together a very pleasant origami meeting. KrakĂłw is a beautiful and delightful city with huge nightlife, and I had a blast. And lots of great food too! For their convention booklet, put together by the gifted Haligami (Halina RoĹ›ciszewska-Narloch), I submitted six CP patterns. I’m posting them here too, for those who might be interested in checking them out.         All diagrams are copyright Eric Gjerde; and are additionally released under the Creative Commons Attribution-NonCommercial-ShareAlike license.    

Moorish Stars - Eric Gjerde

Moorish Stars Crease Pattern

I’ve had this pattern in my head for a long time now, and only recently was I able to realize it in a way that was satisfactory to me. It uses a combination of the hinged-pleat flagstone style and the traditional straight-pleat style that origami folders are used to. It’s based on a traditional Islamic tiling which I have always been fond of, and it’s my pleasure to share the crease pattern with you.

Dodecagon Flagstone CP

dodecagon flagstone CP

Here’s a basic crease pattern for a dodecagonal flagstone pattern, overlaid on top of a triangular grid. The spacing between the hinges is not equal all around the dodecagon, but the actual tessellation itself is the proper dual of the 12.12.3 tessellation (two dodecagons and an equilateral triangle.) What that means is we get two really big spiky 12-sided things and smaller triangular twists between them. I haven’t tried it but if you actually squashed these they would probably overlap! I like them in their “uncollapsed” state, as I think they are more interesting as rigidly foldable constructs… If you want to download the PDF version of this file, you can get it here: Here’s the folded version:

Rhombic Flowers

Hi everyone, I’m getting all packed and ready to head off to Japan tomorrow for the JOAS convention this weekend in Tokyo! They’ve honored me quite a bit by inviting me there as a guest, and I hope to make it a very tessellation-centric time 🙂 I’m looking forward to meeting lots of new friends! I thought I’d post a crease pattern, as it’s been quite a long while… So here’s a full CP for a design a did a while back called “Rhombic Flowers”. I’m not sure I have a finished model of this pattern, it’s just an idea that was kicking around my head; but it looks pretty neat, using rhombus twists to make star shapes. A good exercise in playing with rhombic twists, for sure 🙂 Let me know what you think! It’s on a 64 pleat grid, but by no means do you need to start so large. a 32 grid would be perfectly fine to start, bonus points for doing it on hexagonal paper. (You’ll like the final pattern better …
