But then I popped a hole in the canvas. Not a large one, but an interesting one. And it was pretty close to the center. I talked to my teacher and we looked through the random materials I brought, and chose the pipe and the chain. I put the pipe through the canvas and adhered it on the back with some very strong glue, so it's stuck pretty tight. The chain is screwed to the wooden frame in back, so it's pretty secure, too.
So, this is what it looks like up close. You can see that I framed it.
Here it is from a distance, hanging on a wall in my house. I like it that the chain is long enough to puddle on the floor. The dimensions are 17.75" x 21.5" including the frame, but not including the chain. It leans out from the wall a bit, which lets the chain hang free.
