For my daughters baby shower her theme was rubber duckies. The invitaions were made from a clip art of a little duckie that was copied and put onto card stock with blue and white checked ribbon. The duck was printed in black and white then we colored it yellow with orange beak and feet. We made yellow duckie soaps made in a mold and tied them to a blue washrags with the same checked ribbon, as favors. All the plastic tableware was yellow with blue plastic dishes. Punch was served in a round blue plastic tub with little rubber duckies floating around in it, in yellow and blue cups. We used the large Duckie mylar balloons with yellow, orange, and blue latex balloons for centerpieces. Yellow plastic tableclothes covered the tables The cake had a mommy duck with little ducklings following her. We had bought some little duckie plush easter baskets (discounted from easter) and filled them with bottles of powder, washes and lotions all in yellow, white and blue bottles. It was a lot of fun and a challenge to keep everything in our color scheme but once we started it everything fell into place.
