Remember the line of masking tape down the middle of a shared room? Definitely not the best way to demarcate some personal space for your kids. To head off any nasty tape incidents in the future, do a little bit of smart decorating now.We are loving this wall treatment in this shared bedroom. Using two complementary wallpaper choices on the wall not only sets off each sibling's personal space, it adds whimsy to the room. And don't stop with the wall treatment - choose two complementary rugs or other accessories to let each child's individuality shine through.
