Bring a bit of the forest indoors by decorating a lamp finial with a pinecone, plain or spray-painted silver. If your lamp doesn't already have a basic finial -- the small piece that screws onto the top of a lamp's harp -- you can buy one at the hardware store. 

Lamp Finial How-To
1. Sand the bottom of the pinecone to create a smooth surface. 

2. Dab a bit of hot glue onto the flattened area, and press the pinecone onto the top of the finial.
