One of the best, no-cost ways to redecorate is to repurpose things you already have. Look around your home and think of how items from one room could change the setting in another room. That old trunk in your bedroom might make an ideal coffee table for your living room. With a coat of paint and a set of casters, a bedside cabinet becomes a rolling bar. Maybe that painting in the dining room really belongs in the study. Try clustering items together, like candlesticks or colored glassware, to create a focal point. Seeing your old stuff with new eyes can be fun, and the only thing you'll spend by moving it around is a few calories.
