Metallic Leaf Pumpkins: Collect fallen leaves and spray paint them gold; let dry. Paint one pumpkin white and the other gold. When dry, use crafts glue to attach the metallic leaves to the white pumpkin, then arrange the pair together on your porch.
Add Foliage to Pumpkins - Just use ModPodge to découpage a white gourd with pressed leaves, harvesting the foliage from your own backyard. Or you can stamp on tissue paper and Mod Podge it onto the pumpkin.
