Baby shower activity: make a mobile! Go second-handing and look for unique trinkets or as guests to bring one (something special). Add bells/chimes, beads/old costume jewelry and make a mobile from the eclectic pieces of your friends and family.
Wall paper in the closet. I love creating a closet with as much detail and style that you would spend on the rest of your room. It usually holds some of your most favorite possessions. I painted my closet Hot Pink.
