Creative ways of using paper - part 1

I have created a few things by using paper - boat, cool sunglasses and I've also designed my own iPhone mobile.  My design has 2D shapes of rectangles, circles and oval.

I've folded my paper. I can see there are two triangles. They are also a 2D shape.

Thinking of my next steps.

I've folded my paper more and made a boat.
