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.
DIY Outdoor Solar Light Display : 2 fence posts + 4 solar outdoor lights + 8 extra long screws + an long scrap of treated x wood. great idea for the deck or patio! Would probably use nicer solar lights!
