I'm a graphics design student and for a course I had to make a repeatable pattern. For fun (and to make an extra impressive presentation) I decided to order a shirt with that design on. When researching how to go about doing that I stumbled upon Printful and the concept of print on demand stores and thought I'd give it a shot.
However, I'm starting to doubt if people would really buy this stuff. Since it's an all over design I want to sell the cheapest option on Printful is €25 so I'd have to sell it for at least €29 to make a reasonable profit but that just seems ludicrously expensive to me. I don't think I've ever bought a shirt for more than €10 in my life. I did some research and there are brands that sell similar shirts for more but they are all well known brands, I would be a nobody in comparison.
