Adorable.. Take a 4x4 and paint them orange, I would add a wine cork to the top for a little extra! :)
Dryer vent (purchased at your local hardware store), orange spray paint, a stem (I used cinnamon sticks, but you can use sticks or whatever you want), and a little bit of raffia. I cut and glued the vent into a donut using hot glue. Then I spray painted the whole thing, making sure to get in all the groves. Attach the cinnamon sticks and raffia, you have yourself a cute little pumpkin!
