There are a few ways to stick a magazine to the wall. The most common is to use tape or glue.
Tape is the easiest way to hang a magazine on the wall. All you need is a roll of masking tape or painter's tape. Place the strips of tape on the top and bottom corners of the magazine, making sure they are even with each other. Then, press the magazine firmly against the wall and hold it there for a few seconds. The tape should keep the magazine in place.
If you want to use glue, you can buy special poster adhesive from a craft store. Follow the directions on the package, and apply a thin layer of glue to the back of the magazine. Press it against the wall and hold it there until the glue dries. You can also use double-sided tape, which works in much the same way as regular adhesive but doesn't require any drying time.
