For my son's 1st birthday party, I chose a rubber ducky theme. The decorations, cakes, and party-ware centered around rubber ducks, water, and bubbles. I tied yellow and clear helium balloons to the table and deck.  The yellow balloons coordinated with the ducks, and the clear balloons represented bubbles. I placed boxes underneath the tablecloths to give the table some dimension. I layered a yellow tablecloth on top of a white one for both the food and gift tables. For the centerpiece, I attempted to imitate the party invitations and accessories by constructing a "bathtub" full of rubber ducks and "bubbles".  The "bathtub" was a small aluminum bucket.  I placed one large rubber duck toward the back of the bucket, and smaller ducks around the large one.  The "bubbles" were various sizes of glass ball floral picks (available during the Christmas season at craft and hobby stores). I used poly-fil in the bottom of the bucket as a filler, and put a white infant washcloth over the side of the "tub" to represent a towel. For additional table decorations, I purchased a picture frame with rubber ducks at the bottom and inserted a photo of my son wearing a yellow and white outfit with a duck on it. I also used a rubber ducky bank, and goody boxes that coordinated with the invitations, plates, cups, and napkins. When I stacked the plates, I alternated the rubber ducky design with plain yellow and plain white plates.  I did the same for the napkins and cups. At a local discount store, I found transparent plastic yellow plates and bowls that had tiny bubbles in them, which is what I used to serve chips, dip, and cookies with yellow icing. We also served hot dogs.  I used yellow, clear and white plastic utensils to coordinate with the rest of the decorations.  The goody bags were bubble wrap that were made by cutting a large rectangle and then gluing the sides together.  I gave bubbles, rubber ducks (to the smaller guests), gum in a yellow package, pencils, and card games (such as Go-Fish, Old Maid). I tied the bags with yellow and white curly ribbon. We played "pick-up-ducks" in a plastic swimming pool. The prizes for the game were placed in clear party buckets, and each child chose a prize from the bucket that corresponded to the number on the bottom of his or her duck. Prizes for both girls and boys were put into each basket so each child would have an appropriate selection. Prizes included stickers, water guns, yo-yo's, candy, gum, coloring books, reading books, and rubber ducks attached to mesh bath sponges. Since the party was in August, each guest was asked to dress in their swimwear.  Various sizes of inflatable pools were set up for the party guests to play in, which was enjoyed by all. We also set up a sprinkler that sprayed bubbles along with the water. A local bakery used the invitation as a reference for the cake design, which had a rubber duck in a bathtub full of bubbles. I inserted glass bubbles among the icing bubbles to add a touch of realism. My son's individual cake was blue with white icing piped around the edges, with one rubber duck swimming in water.
