Let's start at the top - the ceiling. Painting a ceiling is a relatively easy way to change any room's appearance. You may want traditional white paint to match or coordinate with the walls, go for a contrast, or use one of the many different techniques available today. Get creative - it's not that difficult to paint over if you make a mistake. You might want to try hand painting wispy clouds on a sky blue ceiling. Or for more drama, how about stenciling gold stars and a moon on a midnight blue wallpaper background. If painting's not your thing, there are tons of wallpaper choices to give the ceiling a different look and texture. Also attaching fabric, straw matting or even lattice to a ceiling will add interest and a personal touch. Acoustic tile is something you might want to consider, especially if noise is a problem. Planks, as with wood floors, add a certain charm and warmth to a room. Adding beams or moldings (either real or faux) might give just the right touch. If you're handy you may want to do it yourself or you might want to hire a professional. It depends on your budget, time and experience.
