In the shirt, she is doing a Chuck Norris roundhouse kick. I thought it would be cute to make the shirt read like the credits of Walker Texas Ranger (it says "Chuck Norris IS Walker Texas Ranger") so I just changed it to Joanne IS the birthday girl we celebrate, with the same look as the credits.
Have you ever heard the Chuck Norris jokes, like Superman wears Chuck Norris Pajamas? I took a birthday themed one for the back and inserted her name.
Stay turned for pictures of how they turned out in real life! I think it will be hilarious! And Happy Birthday, Joanne! :)
