A shirtskirt! You can make one in 10 min with an old, oversized men´s shirt, a bit of thread and elastic band. Cut the shirt according to the desired length (stitch elastic at the top) and fold the top with elastic band. Sew the arms together to serve as a belt/sash and add a few belt loops from the excess fabric.
Cloud lights. This is one of the single most awesome ideas ever. In the comments instructions were given: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.
