I create fairy houses using nothing but plastic bottles, jars, tinfoil, craft foam, hot glue, white air-dry clay (the one that maintains its size when dry) and watercolors.

I use them as cookie jars for my candy bar, but they can be used as baby room decorations or even as lamps if you add some battery operated LED candle lights
