Bookshelves work in large bathrooms to hold towels and toiletries. Metal garbage cans spray painted a cute color and turned upside down also make great side tables. Table cloths and dish towels can be valances, shower curtains can be bedspreads, outdoor furniture and rugs can come indoors.
Wonderful art that pulls your look together can be made for next to nothing. Decor pieces can be created from junk you were ready to throw out if you have some spray paint! Ugly cabinets can be spruced up by taking the doors off and painting the inside of the cabinet a cute color and adding some white dishes.

Bad light fixtures can be disguised with colored baskets or beaded strings.
Sometimes all it takes is someone that knows the image you are trying to portray with your home and who has the vision to get you there!
