After looking at some of the entries for the contest on the Cricut Circle Message board, I don't think I have a chance but here it is.
I used Car Decals for the cricut heads. Birthday Bash for the banner and the font is American Alphabet for the font. if you look close on the polka dot paper is the name of a cricut machine or items. They are Cake, Gypsy, E2, Imagine, Personal, Cartridges, Expression, and Create.
