Souvenirs, Trophies or maybe pictures all need a prominent place to be displayed. Decorative shelving would be a good start but a better start is finding the right tools and materials. A handsaw, pencil, drill, level and tape measure are all good tools to start with. Keep it away from high-traffic areas where it can be bumped into and dislodged.
Draw out what you need on the wall, and be sure that it measures out correctly.
Be sure to mount your wall brackets to the wall stud to keep them from falling out easily.
