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.
I remember making these last winter and hanging them on trees outside in the garden. It would look so awesome when the lights hit that tree and the cranes would light up so perfectly. I want to do it again this summer!
