I'm working on a new T-shirt design for the website members, the following is just an idea for the back of the shirt. It will measure 14 inches across. I call it the "MIDNIGHT F6B" , making it look like it's being lit by the moonlight.
Please disregard the circular pattern coming off the tip of the bat logo, my screen shows a circular pattern that is not part of the design.

The Black, Grey and White tones on the artwork have not been adjusted yet.

The left chest will have a bat logo with just the F6B letters under it and a splash of color.

They will be sold in PAIRS and the estimated cost will be approximately $23-$25 per shirt and the 2X,3X,4X and 5X will be $2-$3 more.

Heavy cotton, short sleeve Hanes Beefy T's. Please let me know if there's any interest.
