How can I decorate my room to make it more "beachy"?

Think of light, bright and airy.This is a very cheap fix, buy an old headboard, or use a piece of pickett fencing for a headboard, paint it white, off white, pale yellow or pale blue, cool colors work best for the walls, but keep them light, curtains should be white, gauze, or lace. Find an old bureau and night stand paint them white, or the old crackled, chipped look is pretty. bedding should be light and bright, you can go darker on the bedding. Good luck and have fun should be able to complete the look for a few hundred dollars.
