The Navajo Three Sisters - corn, beans and squash - are complementary proteins, and complementary plants: the corn stalk gives the beans a pole to grow on, the beans fix nitrogen, and the prickly squash leaves protect everyone and shade the soil. And they are visual complements too. I painted this monumental work, all 12 square inches of it, for a FANS (Fund for Arts on the North Shore) fund-raiser. But then I liked it too much, so I bought it from myself and donated the money to FANS. So I got to be a creator, a buyer and a supporter of the arts - another complementary trinity.
