This is an old project. The idea came from some very random activity.
One day, I was having my usually coffee in Peets Palo Alto Middlefield. I sat mindlessly, relaxing and started using my scissors which I carried in my purse everyday. I had no plan, however, as I cut more and more, clearer and clearer ideas came out. After a few paper napkin, I got this symmetric patterns.
A few days later, I showed this to class. Kids loved it.
