This idea is for an upcoming baby shower for my sister.  I saw some rubber ducks in the store and that was my inspiration. I made her invitations by buying card stock and 3 stamps. a rubber duck stamp was used first with one duck on the lower right corner of the envelope. I then stamped 3 ducks along the bottom of the front of the invitation. My 9 year old daughter and I then colored them. I bought the plates, cups and napkins from birthday express.com. I bought a baby doll bathtub that just happens to be blue (its a boy) that I will use for a centerpiece with ducks floating in it.  The cake is being made at the bakery to look like water and I will place my own ducks on it. I will make yellow punch with pineapple juice, water, sugar and almond extract and will float pinapple sherbet "bubbles" in. The best though is the disposable diaper cake I have made for a centerpiece. I took 60 size one diapers and rolled each one, tied a blue ribbon around each one. they are stacked up to resemble a 3 tiered cake. I tied each decoration on with ribbon which consisted of socks, shampoo, lotion, powder, toys, bottle, soap ect.  I then tied a thin ribbon with ducks around each tier.  I placed all on a cake circle I bought at the cake shop.  The family of ducks I bought was a momma duck and 3 babies.  THe babies will be in the tub or on the cake and the momma will hold the nuts and mints. I have made a couple of scrap book pages to get her started and one has a sign in sheet so we know who was present at the shower. This is the first shower I have hosted and I am having a blast reading these posts for more ideas.  THanks and keep them coming.
