Here is Miss O. She was a package. My mom made her costume with felt and then sewed real packaging labels on.
I always like to make them matching, and since they haven't expressed interest in picking their own costumes yet, this year we went with the package and a UPS man. My mom had this costume in her dress up clothes box at her house, so we didn't end up having to buy a costume.
The festival had all sorts of carnival games. This is one where you had to find the right key for the hole and then you got to open the treasure chest and choose a prize. Look at Bean's face--he's so excited that he found the key. (No need to mention that they let you try as long as you want! ;) )
