Our baby's favorite things are balls, so for his 1st birthday we had a sports theme party.  (I used some ideas from the Betty Crocker Soup & Crock-Pot Meals recipe book - football party ideas)  The invitations were footballs. I took brown craft paper, cut out the football shapes, and crinkled them up.  On card stock, I had printed the words of the invitation in the same size football shape, and I cut them out (I fit 4 football shapes on a page). I put the craft paper over the card stock, used a paper punch and punched 3 holes at the top, and laced the papers together with white curling ribbon.  The invitation read "Come have a ball at _____'s 1st birthday!"    We were able to have the party outside - which was lucky for April in PA. We rented a tent, tables, and chairs.  In the center of the tent, I hung a football pinata for decoration. I made flags that said "____ is #1" and hung them all around the tent.  I also made flags on balloon sticks and put them on the tables. I had bought 4 Easter baskets from Wal-mart that were a football, baseball, basketball, and soccer ball and filled them with caramel corn (which I made with corn puff instead of popcorn so that the babies could eat it), and set them on each table.  And for a flower arrangement,I cut a football at one end, stuffed it with oasis and filled it with flowers, flags on balloon sticks, and curling ribbons. I put that in a plastic container (a Boston Market mashed potato left over container) and put tissue paper around it.  For food we had park food. We had hot dogs with all the fixings, soft pretzels, nachos, and caramel corn.  I made a pan of green jello, and used vanilla icing to make it look like a football field.  I bought a cake and they put the 4 differnt balls on the cake.  I also make cupcakes and iced them as baseballs and basketball and had football cookies.     For games for the 3 year olds, I made a baseball pinata and they used a bat to break it, and then we played "get the soccer ball pass the goalie"   (It was "pin the tail on the donkey"). I drew the soccer net on craft paper and cut out a huge goalie and soccer balls out of card stock. And for the babies, we had every kind of ball in the yard.  For treats for the party, I had bought different sports balls at our local craft store each child got one.  The bigger kids also got wiffle balls and bats and sports ball chocolates and the little kids got baby food cracker/puffs and a roll-a-around ball.    We had a great time.  I hope any of these ideas helps someone else out!
