DIY - Glow in the dark pots with mums for fall/Halloween. Buy a flower pot that you really like and use Rustoleum's Glow-in-the-dark paint to paint the pot. During the day, the paint will absorb the sunlight and at night the pots will glow.
What a cool idea this is! Outdoor Chandelier: Replace the light bulbs in an old chandelier with inexpensive solar lights & hang it from a tree branch. You'll have gorgeous outdoor lighting without having to hook up electricity.
