I am going to do something like this as a "feelings" extension. Whatever color they "feel" that day (black--grumpy/ sad, etc.) They add. Would be interesting to see which colors they associate with which feeling and why.
Cloud Lights - First, you need some cotton batting, a paper lantern, and three flameless candles, the type that Glade sells. Pull at the cotton batting until it looks fluffy, light, and cloud-like. Then, hot glue it to the outside of the paper lantern in various places. Make sure it´s fluffed to your liking, then light the lights and stick them inside. Hang the lantern wherever you´d like.
