Crappy t-shirt designs. I have a bunch of random shirt designs (I am no designer, just made some mediocre SVGs with funny ideas I had in Inkscape), and sell them on the German spreadshirt marketplace, makes about 20 Euros/month.
Most of them trivially translate to the English-speaking market, I should really do that. Does anyone have a hint where the best place to sell 'low-end' t-shirt designs in the US is?
