If you have an old bookcase that needs a little dressing up, then consider decoupaging it with photos or craft paper. You can do this in a variety of ways, using acrylic paints, glue and a decoupaging medium of your choice. Make sure you do your project outside where your bookcase can dry in the open air and where you can breathe in fresh air. Varnish your bookcase with a polyurethane coat, which will make it shiny and will protect your decoupaged work.
Spread out your tarp in an outdoor space. Place your bookcase on top of the tarp. Put on your goggles and a mask to cover your nose and your mouth.
Paint your bookcase a solid colour such as white, black or red. Allow the bookcase to dry.
Cut out photos or craft paper. Apply découpage medium directly to the bookcase with a sponge brush. Press the photos or craft paper into the medium. Move the photo or paper into position. Cover with more découpage medium, smoothing out clumps as you go. Allow the medium to dry.
Coat your bookcase with a polyurethane varnish to create a solid, shiny finish.
