A gallon or two of paint can completely transform an entire room for around $100. 5. Declutter and reorganize. (That alone can make a massive difference.) 6. Spray paint your light fixtures or swap your lamp shades for a new lighting look for less. 7. Refresh just a few textile pieces - throw pillows in the living room, a comforter in the bedroom, or the shower curtain in the bathroom. 8. Swap your rugs from room to room. 9. Add a few plants. 10. Do a furniture/decor swap with your friends! Put post-it notes on items you're willing to let go of and shop each others' homes for a room refresh without spending a dime.
