craftgrrl | my baby shower! I need one more idea

I am having my third bebe. I already have one boy and one girl so I dont really need anything that is usually given at showers.

My sister and I are throwing a shower like party for me. As far as the guests know they are being invited to a luncheon for fun. When they get there they will be able to choose from 3 craft projects that will be made for the baby (a girl.)

Project #1 will be to make origami paper cranes that will be made into a mobile.

Project # 2 will be to decorate onesies...I guess with fabric paint, etc.

Project #3? I'm not sure about....which is why I am asking you wonderfully creative innovative unique artsy gals for help. I have a couple ideas but they are not very clever. I welcome all ideas and will post pics of the final projects when they are done.

thanks
