T's
I've made a few t-shirts as you can see here and here. Some have sold, some have sold quite a few, some have not sold.
The BLM t-shirts and NASA are the best sellers.
All proceeds for the BLM t-shirts are donated to BLM.
Although some do not sell, it does not bother me. Designing t-shirts is something I have always wanted to do, I am proud of them. Just doing my thing.
Advice, do your thing, regardless of trends and pressure. Do what you love.
