Fences and Nests #18 is the latest addition to my Fences and Nests series. I made it for my son, who just received his PhD in Mathematics, because he told me he likes hexagons. Fences and Nests #18 is mixed media on cradled board, and it measures 10" x 10" x 1.5". The background is a monoprint of a plastic hexagon garden fence, the dark hexagons in the lower middle is a scan from my vacuum cleaner air filter, and the colored stuff at the top is the "nest" that's made out of leftover threads. It needed the nest at the top for balance.
