What do you have in mind for the style and theme of the t-shirt?
I want it to be something fun that people will want to wear. I'm a chiropractor and I do a lot of cupping on my patients so I wanted to make t-shirts that say something like "I survived cupping at Elevate Life" with a picture of an octopus tenticle (since the cupping bruises look like octupus suction marks) in the shape of a spine. Now this is a high end clinic so I want it to be a little goofy and a joke but not cheap looking, overly cartoon networkish or like something you got at a carnival. Currently I'm not sold any one color scheme. The colors on my logo are black and royal blue, so it will probably be on a gray colored shirt. The logo will be on the back so no need to worry about incorporating that into the design.
"I survived cupping at Elevate Life"
Then some rendition of an octupus arm or tenticle preferable in the shape of a spine.
