I didn’t like this model at first, as it wasn’t what I originally wanted to do. But with the addition of the teeth and the shaping of the back, I find it far more endearing.
I’d probably say my preferred design method is doodling. I like just folding until my unconscious mind thinks of something.
My book, The Bases of Folding, is a callback to older origami books and a thank you to the community that has given me so much. It features models I have designed throughout my life. It is available for free, with an optional donation, on my Google drive.
