Origami Peacock Spider

I was inspired to design this when I watched this cute video: https://www.youtube.com/watch?v=HYFQQB9vqPw

The spider looks funny and rather, cute.

Design

I wasn't worried about the legs since they should be straightforward. So I started with the abdomen.

The abdomen needs to be color-changed, and then color-changed once more to draw the pattern. I was inspired to use windmill base, since some people in Origami-dan like to use it for designing 2D color-changed models. Windmill base is versatile because it has 4 flaps which fully cover perimeter of paper, and as we know color-change is normally done on perimeter.

Windmill base. See the grey part on folded model shows the paper perimeter.

Now I just need to make similar flaps that is from paper perimeter. This is easily done on box pleating with array of 1 unit flaps:

Five 1-unit flaps that is usable for color change.

Finally to make the pattern, I strip grafted the flaps to add extra perimeter. It is shown on the CP.

To get the top strip, do a reverse fold and slightly lift up the corner.

For the "circle" and dot, start from reverse-folded shape like before, then improvise.

And finally the bottom strip is just fold up.

Just be sure to fold it accurately! The one in picture is very sloppy and just for demonstration purpose.

For the eyes, there's a way to make seamless rhombuses.

The main challenge of this model is accurate and symmetric fold. My dexterity and fine control is still low, so the result isn't as good as I imagined. Some time in the future I'll refold it after I grind with more models.

Warped and Wrinkled Paper Curse

After starting using Carboxy Methylcellulose (CMC), I began to wonder if my setup wasn't right. The problem was my double tissue would always peel itself when drying. There will be high pitched popping sound from the paper every now and then. Finally it would be completely off the surface. Whereas on every tutorial I saw, the paper will still stick to the surface and we have to peel it off. The bad part is the paper will be warped; it's not flat. It is difficult to fold a straight line on paper like this. Imagine precreasing a grid or locating references when your fold can be bent due to the paper's bump. I have theory on why the warp happened. Before going to that, it is important to know that: When a paper is wet, it expands. When it dries, it will return to the original size. However it will keep its shape when it is wet, meaning that if it is bent when wet, it will retain that bend when dried. When my paper dried partially, that region will shrink. This created differe

Origami Ibex

Ibex is a type of wild goat found on Eurasia and North/East Africa. Easily identifiable by its long curved horn full of ridges, which is what I'm trying to express here. Nubian ibex is vulnerable to extinction due to competition with livestock and habitat loss. Ibex has been nearly extinct multiple times in the past because of hunting and unable to compete against livestock. The most recent extinction was Pyrenean ibex, in the year of 2000. Image source: https://animals.sandiegozoo.org/animals/nubian-ibex I want to make my model to be instantly recognizable as an ibex, not a goat. Horn ridges are rather specific for ibex, so I tried to represent that with spike structure commonly used on insect legs.

Origami Markhor

More detailed crease pattern to show where to pleat the neck. Markhor is a type of mountain goat found in Central Asia. They have curly horns which can vary from simple twist to a tight corkscrew. The male has long and shaggy mane, similar to lion. I had an idea to design a markhor after finishing my ibex and folded Kaito Nagayama's chameleon, whose eyes are made by wedged pleats to form spiral. So what if I use the same technique on goat's horn? It worked in theory and my test fold on foil (shown later in this post), but not on the final fold. In the end I just curl the horn.
