We love this take on a DIY mobile for a baby's room. It's simple, inexpensive, and makes a statement without overpowering the room.
Jessica Flannigan, who blogs at Live the Fancy Life, created this piece for her son's room. While it's not a mobile proper, Jessica designed it so that it is visually interesting from all different angles. She suggests hanging the lanterns one by one so that you can control the look and shape of the piece.
