Introduction: Post-It Origami Icosahedron

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

Step 1: Fold Post-it in Half Glued Side Inside

Step 2: Fold Bottom and Top in the Center

Step 3: Fold Both Corners on the Upper Line

Step 4: Wrap It Up

Step 5: Fold the Corners Over

Step 6: Make a Square and Fold It Into Triangle

Step 7: Make 30 Sonobe Units

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

I got stuck when I was trying to put it together, but then I finally got the hang of it after an hour.

Will it still work if I use origami paper?

If was kind of hard but I got it all the piece to fit together, I feel so accomplished.

Connecting can be a little challenging sometimes. Just connect pyramids together in cycles of 5. It will begin to curve into a ball or start with cyckle of 5 pydamids and turn it over. Then add units in the "side/middle". To close icosahedron you will need to connect pysramids next to each other and then add in the gaps more units. In which part did you had trouble?

I'm confused on how you would make the pyramid shape. I have 30 of them sitting in front of me. I just can't make out how you did it...

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
