I suggest.

Pictures of your favorite bands and actors.

Pics of you and your friends.

And a shelf.

Simple and easy.

While at Michael’s get Mod Podge adhesive glue and glue down cut out pictures of you and your friends or magazine cut outs. After they are glued down, paint a layer of Mod Podge over the top of everything and let it dry. This will seal the project and it will look really nice. I have done this type of thing for years. It will make your locker look awesome if you hang up a project like this. It something you can do with some friends so all your lockers will have that personal touch.
