Yes, the ideas are a little Yuppie, but this will get you started. . .
I really like the idea on her website about having guests use a fabric pen to write their initials on small squares of fabric. Then someone embroiders the initials and sews it all up into a quilt!
My sister told me about a cool game where in the invitations you ask your guests to bring a picture of themselves when they were a baby. Then you have to guess who the pictures are all of, whomever guesses the most right wins a prize! Fun to see pics of other people when they were little.
You definitely need to get one of those books, or check out www.babyshower101.com
. Have you considered using a digital camera to take pics of the stuffed animals to create your invitations? You can attach vellum with a ribbon to the stomach of the animal picture to display all the necessary invitation information. Then maybe make cupcakes to match the animals using candies and what not, martha's idea. . .
