Jack in the Box Costume

I made this costume for my son, Braydyn who was 8 months at the time. I was looking for a costume that would work with this stroller since he was not walking at the time. I looked online and found the idea for the costume, but there was not much instruction. I used foam board for the sides and poster board for the design, just glued them on and copied the design straight from the Jack in the Box toy. We used floral wire to attach it to the stroller. I then just ordered a 3.00 clown costume off of Ebay.
