Aaron and I made invitations to Jakob's 1 1/2 Year birthday party. Because he was born on December 22, his birthday gets lost during the holidays. His half birthday gives him a party that is not rushed.
We used card stock that cut 4 1/4" by 5 1/2" as the base. The front of the card has the car, balloons, and the sign. The back of the card has the party details printed from the computer. Aaron designed the front of the card.
