Good luck.
I will check out your campaign and donate. T-shirts are a tough business because it's such a competitive market, but nothing is impossible. So be encouraged to continue to go for your dreams.
If you get a chance check out this campaign and tell me what you think - I want to hear from a young mind on this one.

Best.
