## Introduction: Post-It Origami Icosahedron

Here I show you how to make origami icosahedron from 30 sonobe pieces.

## Step 8: Place Three Units Together to Form a Triangular Pyramid

Make them in cycle of 5.

## Step 9: Build It - It's Like a Puzzle

Just form triangles and you will see form shaping.

## Step 10: Alternative Method for Building

You can also build 2 cycles of 5 pyramids separately. In one of them connect middle from pyramids and then connect the top from ready cycle of 5 pyramids.

## Step 11: Now You Have Nice Modular Origami to Decorate Your Desktop

what does in mean in cycles of 5? im really stuck on putting it together

i decided to make it from top to bottom, but i can't seal the last bit and i lost tracck of
the amount of post it notes i had

How do you fold it like it says in step four?

fold top right corner under bottom flap

i wasted 2 hours making these units to find out that i cant make a triangle :_(

Thanks for this! It took two frustrating hours, but I managed to complete it and I'm very proud of the result. My origami pride and joy :)

I've done this with notebook paper and it's a little different. Step 4 loses me. I understand the first fold. Then the picture of the second.... Lost

I've made many of these, with 3 pieces, 12 and 30.
Do you know what the next size up is?
I'd been told it's 72 but I've tried that before and the ball was less than half finished.
My current attempt has left me needing to buy some more post it notes!
These are great fun to make and they look absolutely awesome!!

Does anyone know how to do step four? I got the first part but then that second part... 😂

got stuck trying to put it together, also this is not a icosahedron, because an icosahedron has 20 faces, meanwhile this one has 60, 3 per triangular pyramid

i would click i made it but i just tried i didnt really make it
