We were lucky enough to watch this incredibly detailed process on and Art Adventures summer camp tour, by happy accident. I’ve attached a link to the process if you are not familiar with his work, his instructions or his new Wall Drawing #370 at the Met!

We were there on days 10-14, when they were “inking” in the black. The crew walked us through the process, showed us their materials, the written instructions (this was cool) and were fabulous with the kids and their questions! (and ours:)
