Knowing how to cut and fold triangles are great but you need to know how to use them as well! Here are a few of the most used building techniques in 3D origami as well as how to read/draw your own diagrams.

Almost every 3D origami piece will be built in the shape of a circle but it is hard to turn a 3D object into a 2D diagram. Therefore, diagrams are drawn like rectangles in order for you to see both the front and backs of pieces (like the label on a can being peeled off). The ends of the rows are supposed to be connected to the opposite sides, but obviously you can’t draw that so remember that they are connected.

When making your own diagram, Copy->Paste will be your best friend because it takes far too long to draw out individual triangles. The paint bucket tool is pretty cool too.

Increases are used when you want to add pieces to onto a smaller base so the structure starts to look like this: ▼. In the opposite way, decreases are used to reduce the number of pieces you have so the structure will look like this: ▲. Do note that you’ll want to space out increases/decreases from each other and do them over several rows, otherwise if you do them all in one row it will become way too packed or that row will look like it has holes. Spacing increases/decreases also makes it look more natural.

I currently do not have the pictures used in the video but I will update this post later when I get hold of them.

Shout out to Jewellia7777 once again for coming up with some of these techniques and inspiring me to continue in this craft!
