I recently took at class from Jennifer Moore who is a well-known weaver, she weaves beautiful pick-up doubleweave. See her work here. The class I took was titled 'Math-magical', we studied lots of geometry, symmetry, angles, the golden proportion and more - I'm still trying to figure out how to apply
what I learned to my weaving. What I did get from the class is a new way of looking at the world.
The last day Jennifer showed us these paper weaves she had made. They are amazing. I would love to know how she did this. Maybe someday she will teach a class in paper weaving.
