Walls provide a thin barrier between the material world and the abyss. Reality is not solid, but a thin platform: heaven is above, below and behind. A stabilizing shaft appears and temporarily disappears and reappears after passing through the walls to continue into the void. Pinned is from a series of 3D paintings. The paper is cut and folded to extend beyond the flat plane of the painting. The openings are backed with heavy silk. The inky blue-black is antique silk velvet.
