In terms of size, this is my most ambitious project to date. The three large triangular pieces are about 6-8 inches in diameter and altogether, it is between four and five feet wide. It’s also fairly heavy–perhaps ten pounds give or take–so I’m a bit surprised that it doesn’t pull the hook off of the ceiling, which is only held by adhesive. It may come crashing down some day, but hopefully I will be able to find a home for it before that happens. The paint is acrylic.
