Origami Icosidodecahedron, No Need for Glue

Hi, this is my first instructable so apologies if this confuses anyone :)

No scissors needed, or glue, or paper-clip or....well any other type of fastener because the interlocking folds do job perfectly. Great ornamental pieces that can be hung up or turned into a lamp, try using different colours, sizes and patterns.

Equipment:
Paper squares (30)

Time:
~1.5-3hours depending on size.

Btw sorry for the terrible resolution pictures, I dropped my camera in a peat bog so I had to use my phone instead.

Step 1:

Making squares. The pictures are pretty self explanatory. Experiment with different sizes but this size makes a small hand-sized ball.

Step 2:

Step 3:

This is the base of one module.

Step 4:

You have to make 30 of these to make the ball shall, if it took you along time to understand it, have fun!

Step 5:

Some trial and error may be used first time, but the general idea is pentagon, triangles on pentagon's sides.

It looks great on fireplace or windowsill or strung up on a ceiling, I normally put LED lights inside to make it a lamp.
