About T-Shirt Design
The message on I DO A THING CALLED WHAT I WANT! Tee is simple, but it has enough personality to stand out. It fits really well with everyday humor, but you do not have to be obsessed with that stuff to enjoy the joke.
It makes sense for birthdays or casual days, especially if the person already likes this kind of humor. For a funny t shirt, it keeps things pretty straightforward and lets the saying carry the humor.
It is an easy design to wear when you want something a little more fun than a plain shirt.
