There are some times when you see someone do something, and you think to yourself “why didn’t I think of that?” It’s usually some clever little trick that doesn’t require a lot of effort, but yields great results. Take, for instance, the act of hanging a picture or poster on your wall. Frames are a nice way to go, but they are expensive. You can try push-pins or Sticky Tack, but those will harm the paper. So what other option do you have? Magnets.
This great Instructable shows you how you can use push-pins and magnets to hang posters on the wall without damaging the paper at all. The only work you have to do is gluing the tiny magnets to your pins, and letting them dry. Then just put the pins in the wall, put your poster up against them, and then add more magnets on top of the pins. Alternatively, you can glue the other magnets to the back of your poster (as they showed in the guide), but again, that can damage the poster.
