Hello, my question is are you looking for a new logo and something for the back of the shirt or is this job just for the back design?

using the logo (you can make tweaks if you like) and creating a tshirts

hello thank for the invitation sir, one question
did you just need design using your logo, or do you have quote,slogan or website, that you want include in the design ?

Using my logo and any tags I have shared on the T-shirt pic... addition all I have my own tag... make big commitments take big action to create big ass results
