My son turned 12 and was too cool for me to take pictures at his party. But also thought he was still young enough to have a "fancy"party. He wanted a theme and decorations, favors and the whole shebang. I didn' have the heart to tell him I thought he was outgrowing it so I talked him into a rock climbing party. The boys had such a blast and I wish I had pictures darnit. We contacted to local YMCA and it was only 5 or 6 bucks a kid and they let us bring cupckes and pop in.
I didn't want to make a scrapbooky type cutesy invite for a bunch of 12 year old boys so chase drew and awesome pic of a guy rock climbing and we printed the words on it and made copies. It was just right I think.
