To help protect walls in a kids' room, a variety of fun and durable display surfaces can be employed. Do-it-yourself blackboards, magnet boards and cork boards not only provide a great space for showing off kids' crafts and activities, but they'll help prevent permanent damage to the wall surfaces. The panels can be removed easily later to return the space to its former use. Create simple chalkboard panels by painting pieces of sheet metal with chalkboard paint, available at home centers or craft stores. To create a magnet board, cut sheet metal to size and affix it to plywood using contact adhesive. Use tin snips to cut sheet metal. Whenever cutting sheet metal, be certain to wear work gloves as the metal edges are very sharp. Create a corkboard panel by attaching cork tiles to plywood using construction adhesive.For display panels made in this way, cover the rough or sharp edges using wood trim. Framing the panels in trim also provides a means for anchoring them to the walls. Anchor the panels to the wall with wood screws, making certain to secure them to the wall studs, not just the drywall.
