11: Pop a Wallpaper Bubble
It's finally time to do something about those air bubbles under the wallpaper that your "handyman" brother-in-law so thoughtfully left behind. Make a tiny slice through each bubble with a sharp razor knife, then take an artist's syringe—a plastic, needle-tipped tool available from craft shops—and inject a small amount of white PVA glue (like Elmer's) behind the paper. Smooth the area with a wallpaper brush or a dry paint roller, and use a damp sponge to gently wipe away any glue that squeezes out. Your brother-in-law's handiwork will never have looked better.
