Update: I am currently in professional school so my post frequency will probably slow down!


I am an origami hobbyist currently interested in origami design. Whenever I have some free time, I try to improve these skills through the practice of various origami techniques and designing origami models. My designs are often based on whatever strikes my interests, such as video games, television shows, and objects in real life that are not commonly done. This gallery is my way of having my creations and some of my notes online, as well as a way to share with others what I have made. I occasionally accompany my designs with at a crease pattern, and in rare cases a guide or instructions.

Occasionally I'll post designs by other artists that I've folded as interest pieces, which will be indicated in the description and in brackets in the title.

Don't take anything I do seriously. =D


WIPs, alternate views, and extra-silly stuff you don't see here go in my Tumblr:

I just found out my monster hunter origami has been featured on Capcom's blog. If you've come to this page from there, hello visitors! If not, hello anyways!

Gramophone by Cahoonas
Gramophone
Folded from a 13.5" uncut square of elephant hide


An entry for the origami forum’s monthly challenge of curved shapes and surfaces. I’ve always thought the horn on old fashioned record players looked nice so I tried my hand at recreating the shape. Structurally, it's pretty much just a box with a group of pleats sticking up off the side. Twisting the pleats gave us the bell shape, and an elias stretch with the rest of the pleats gave us a needle and arm. I also managed to fashion a record from a couple extra layers on the box. The horn and curved box sides were wet-folded into place. Since I knew I would be wetfolding curved surfaces, elephant hide was the ideal choice.

Red Blood Cells by Cahoonas
Red Blood Cells
Each model folded from an uncut 9" square of red pacon 

A couple of red blood cells. Relatively simple in structure, I wanted to see if I could replicate a biconcave shape that was fully enclosed. This meant that popping out the curved ring around the edges was a tricky task. I'm pretty happy with how it turned out.

If you want to give this model a try, I created some photodiagrams here: fav.me/d8kixes

Vertebra CP by Cahoonas
Vertebra CP
Crease pattern for my vertebra model: Lumbar Vertebra

Built on a 16x16 grid, if you collapse the base, it comes out pretty boxy. The rectangular box that would eventually be the vertebral body is 2x1.5x1.5 squares. I truncated the corners of this rectangular box to round out the top/bottom views. The pleats at the top of the square wrap around and tuck into two triangular slots inside the box.

Flap-wise, this crease pattern includes 3 flaps per side:
Spinous process: long flap pulled from the lower corners of the square. The two flaps wrap around the foramen and combine via improvised tab-slot
Transverse process: pulled six units up from the base of the square at the sides
Superior articular process: a middle flap embedded in the transverse process flap
Posterior articular process: technically not included here due to it being less prominent in some vertebra. I used a elias stretch on the long spinous process flaps to get a 1 square long flap for this.

I've tried folding the thoracic and lumbar vertebra from this base; I preferred the lumbar.

This is what the crease pattern collapse looks like: imgur.com/a/mYghu
In the last image, the flap assignments are:
Bottom two flaps: spinous process, these flaps come together
The two short stubby flaps right above that: are actually two flaps embedded inside each other. outer flap is the transverse process. Inner flap is pulled out to make the superior articular pillars
The rectangle above that: vertebral body
The rest of the pleats above that: extra paper that is wrapped around and tucked inside the body to enclose the vertebral body.

Lumbar Vertebra by Cahoonas
Lumbar Vertebra
Folded from one 16" uncut square of off-white Kozo paper

So I've been studying anatomy and had quite early on come across the spine. I found the spinal segments, or vertebra to have quite interesting shapes and tried my hand at recreating it in paper. There weren't that many spine origami models out there (even less that are human) and thus tried my hand at recreating a relatively accurate representation of this bone. Of course, the challenge was to recreate a relatively complex and curved organic structure using only a single uncut square. Since the vertebral body was a portion of the model I wanted to keep 3D and fully enclosed, I designed this model from a box pleating approach. The vertebral body was formed from a 3D rectangle with the corners truncated. Aside from that, the rest of the flaps were shaped around the vertebral foramen and come together again at the spinous process. I'm actually surprised with how well the whole thing holds together. Aside from the truncated corners and the vertebra body being a little tall, I'd say I got as close to the real thing as I could have.

Hey, if it's not a hassle, could you release some pictures of the collapsed bases for the models that you have CP's for? I'm new to crease patterns, and I would love to be able to make some of your paper sculptures
