Shopping for furniture at thrift stores, flea markets and garage sales is a great way to reinvent your style on a budget. Whether you're going for mid-century modern or rustic-chic, you never know what hidden gems you'll uncover for a steal. Even if the piece isn't perfect, don't fret. With a good sanding, a coat of paint, or even new upholstery, a thrift store treasure can be transformed into a work of art. Plus, going vintage is going "green" so you can feel good about your purchase.
