I'm trying to put up a huge bulletin board. One that basically fills most of one wall. I want to use one big piece and then separate it into sections with border. I am realizing that I am TERRIBLE at putting up bulletin boards, and I think it is because I've never had to do it (at least not a big one). Since we rotate rooms every three months, we've had the same boards up for two years. They are worn out to say the least. Any tips for getting a humongous piece of paper up on the wall (oh, and straight)?
