For my daughter's 10th birthday, we are having a Gease/bowling party.  We are holding the party at the bowling ally.  Everyone will be asked to dress in 50's attire.  The bowling ally will supply all the invitations, plates, cups, napkins, and thank you cards. The kids will eat pizza and cake and then they will get an hour of bowling time.  I got some free bowling pins from the bowling ally (old ones they were going to throw out). I'm going to paint them and fix them up to give as prizes for first, second and third place bowling scores (we'll have the bumper guards up!)  The birthday child will get a special birthday bowling pin as a souvenir. We are going to have a 50's car outside for pictures which we will send to all the guests along with their thank you cards. To incorporate the Grease theme, I'll just put pictures of the characters up in the party room.
