I didn't want to spend money on lamps and had holiday lights around the house anyway. In a pumpkin shaped glass jar we stuffed a string of amber lights on a green cord (interior lights for a tree) and then lined up three glass jars and coiled a single string of Christmas mini lights into them (300 lamp outdoor icicle lights really put out a lot of light and have a nice white cord). As you can see this is simple and versatile, and really pretty. The lights get warm but not hot, after leaving them on for several hours at a time.
