In size, if nothing else. The kids' Vacation Bible School needed a couple murals for a backdrop, so I volunteered to pitch in. I wasn't the only one – a bunch of the older kids painted a lot of other murals. It's just that they could use an overhead projector to trace theirs, but I had to make these two up to fit a certain space. That being said, they did an amazing amount of work, very quickly.
This is me at home, working on our newly finished floor. I could only do that without fear because of what I'm painting on. It's some kind of weird plastic wrap/paper napkin hybrid that lets no liquid through at all. I have no idea what this stuff is normally used for, or why it's produced in such large sizes, but it works great for impromptu murals.
