For my 3 yr old girls birthday party we celebrated it the Disney way.  We had just returned from Disney and we had lots of Memorabilia. I first started with the invitations by making a Minnie face out of my daughter and Minnie's picture at Disney , took black paint and made the ears and wrote on the front. Hip Hip Hooray It's Macey's 3rd Birthday. Then on the inside I told where when and time and listed it would be at the (last name) Magic Kingdom and asked all guest to come dressed as their favorite character or in their favorite t-shirt. It was a big hit. Most of the kids dressed up from Minnie to snow white to Peter Pan. Others did wear their Disney shirts. We had this in our garage and I had it decorated with all kinds of Disney stuffed animals( hanging from ceiling to on the walls.) I had party hats from the 2002 new years celebration at Disney.  We had posters of the birthday girl with all the characters. Posters with all the chef Mickey menu, hopper passes. We had the Disney party decorations and a sheet hanging up saying Happy Birthday.  We had a Castle cake with the magical candles and watched the Disney parades on TV while eating. We played pin the nose on Minnie. It was really cute. I bought the round Styrofoam circles and made a Minnie head out of it . Drawing a face on the big one and putting the two small ones behind and holding together with toothpicks. I colored the little ones black for the ears. I bought the tiny balls and painted them black and put toothpicks through them and they played by sticking them on with the toothpicks. It was really fun. I ended the party by opening gifts and giving out Disney treat bags. It was great and they all had a Magical time.
