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.
Origami Crane Mobile-The Japanese say that you need of these for good luck. This mobile has 7 which is also a lucky number. I think I might actually be able to make 7 paper cranes to make this beautiful mobile!
