Origami

I was about 5 years old when my mother gave me my first origami book. The geometry and precision of the folds has fascinated and intrigued me ever since.
The primary folding pattern that I use for the dollar bills which I have complicated and developed was designed by Jeremy Shafer. Each piece is folded by hand and can take from 30 minutes up to several weeks to fold.
The tiny cranes are all folded by hand using no tools or magnification.
