For my son's 3rd birthday in November we went bowling. I rented six lanes at a local bowling alley and the party guests got to bowl an hour for free.  \*(The birthday boy had a lane to himself--he hasn't quite yet grabbed the concept of waiting and sharing)\* I made the invitations on my computer. I found a picture on line of a bowling ball hitting the pins and they read: "Please 'spare' and afternoon and 'split' to a party as we celebrate Jacob's 3rd Birthday" with the location and time and rsvp following.   The party started at 12:00 and the pizza's arrived at 1:00. I wasn't allowed to bring drinks they had to be purchased there--which saved me some money! After the pizza's we sang "Happy Birthday" to the birthday boy, and cut the cake.  My son couldn't wait to open his presents so he skipped the cake and ripped 'em open.  I didn't have a lot of decorations. I had a tablecloth for the gift table and the cake table.  The cake was purchased from walmart. It was decorated with white and blue icing and candy sprinkles. It read Happy Birthday Jacob.  And I purchased the bowling ball and pin candles from Birthday Express and put them on the cake which was really cute.  There was a prize for the best bowler, the worst bowler, and the first strike.  And for the prizes I purchased an inflatable bowling game for each winner from Oriental Trading. Along with that, the winners also received a card game and some candy. But the best part of the party was obviously watching the little kids bowl. They really had a lot of fun.  As well as the adults.
