For my daughter's first birthday I wanted to do something fun for her but she didn't really have a character that she was into so I decided to go w/ "Balloons" as her theme. The planning started w/ the invitations. I personally made the invitations in the shape of balloons and wrote on each balloon "Guess who's turning ONE" then " There will probably be cake on the floor" and on the next "Inflate the balloon to find out more." When you opened the invitation there was a deflated balloon inside.  Once you blew it up it read information re; the party(date, time, etc..). The decorations were all primary colors w/ streamers and TONS of helium balloons all over the house for the kids to play w/ also to take home after the party. The kids loved it! The cake was in the shape of a balloon and I made round sugar cookies w/ glaze frosting. They were each decorated w/ mini M & M's and drew strings below them w/ a big number 1 on it. The theme didn't end when the party ended! Thank you cards were made in the same design as the invitations along w/ a picture of my daughter in her "birthday suit" eating birthday cake w/ balloons in the background.
