About T-Shirt Design
I always Carry a little Pot with Me T-Shirt works because it sounds more like something a real person would say than a random slogan. It has a clear everyday humor vibe, which makes it easy to picture as a gift or something to wear for fun.
It works for holidays and casual days, but it is also the kind of shirt someone could wear whenever they feel like it. This funny t shirt is simple, easy to read, and does not need a huge setup for the joke to work. It feels casual enough for normal days but still has enough personality to get noticed.
