1. Buy marked down flowers and display in vase. Many supermarkets mark down flowers as they age. I have even ran into flowers being sold at Aldi's for $1 a bouquet. Use on the center of a kitchen island, dining room table or even a dresser in your master bedroom for extra ambiance.
2. Decorate with fruit. There are so many colors and shapes to choose from. I have a wrought iron fruit stand in my kitchen, a fruit bowl on my dining room table and this Southern Living compote I keep on the center of my island.
3. Keep it clean. Any home will look instantly better with minimal clutter, sparkling sinks, and clean floors.
