The sky hopper was one of the last figures I created for my first book. I wanted it to be simple enough so someone with no origami experience would be able to make it. Again I had to balance design and appearance. There were actually several designs that were close to what I wanted, but none that were just right: either the wings were in the wrong place, the cockpit was too short, or the figure was just too complex. One day at work, I was working on one of these failed attempts when I was needed back sooner than I expected. I hurriedly put the figure in my pocket. In the process, believe it or not, I accidentally added a new crease. While it wasn’t the right fold, it did point me in a new direction that lead to exactly what I wanted. There was a lot of luck in the writing of my book but I’m still willing to take full credit for it.
