If possible, it is always a great idea to paint your walls neutral colors like grey, or beige. Stick to the rule of odd numbers. One large item or grouping 3 or 5 items together works best for accessorizing tables and shelves. Balance and contrast make a difference. A dark table is complimented by light accessories and light tables can be grounded and interesting with colorful objects that play off of an art piece in the room. If you are lacking art, mirrors are always a great choice! Replacing old or outdated bedspreads can make a big difference in the attractiveness of a bedroom. Add lamps to brighten dark corners.
