Design: Jorge Jaramillo (georigami)
Modified from a square to three dollar bills.
This one was a challenge from Jorge to adopt his model to a dollar bill. The model is made from a square and was too complicated to adopt to a single dollar bill. After several attempts decided to cheat and instead of one dollar, use three. And it worked perfectly. This is a simplified version of the original model. Now that I figured it out, I will be working on the version similar to the original.
Thanks Jorge for the challenge!
