I'm new to the design and t-shirt industry. I have been playing around with Photoshop for a while and I enjoy it. I would like to start a dj/beatmaker culture t-shirt brand catering to the urban streetwear scene and im wondering if I should focus more on getting in depth with Photoshop or Illustrator first. Let me know your opinions. I already have some experience with Photoshop but I am pretty new with Illustrator.
