Here are several ways - I have none on hand, bummer!
To make a very cool Victorian-like ornament, the base is a lightbulb, a dishsoap cap and a bottle cap. Very cool!
Glittered Lightbulb ornaments
Snowman Lightbulb ornament or this snowman
Angel Lightbulb ornament or This angel ornament
Penguin Lightbulb Ornament
Santa Lightbulb Ornament
Grinch Lightbulb Ornament
I am sure the possibilities are endless.
