Pottery Barn has always been a great inspiration for unique wall decor. They use everything from baseball bats to seashells. Good art can get really expensive, so when you are decorating your walls, think outside the picture from on what you can use. Do you have any funny pieces of driftwood that you could hang? What about hooks with lanterns on them? Do you have any cool wooden crates that you could attach to the wall for hanging shelves? Think about things that will add depth and texture to your walls.
