[sterling77]

Hello, Im young(16 to be exact)and Im thinking about making a small t-shirt business. Just spray paint and blank shirts pretty much. Punk looking if you want a better picture of it. I want to sell in my home town but even though I know people would be friendly towards it, I dont really think there's much of free netflix tech news android 9 an audience for that kind of stuff where I live. Im considering going to a few cities and finding a store where I can have them sell it and they get a share of the profit but I have no idea how that would work out. Of course there's selling online and I would do it but in all honesty Im a bit intimidated by it. And whats worse is that I dont how to run a business in general. Any tips at all would be very well appreciated.
At least I dont have to worry about this being my income, its more for pocket money and expression if anything.
Apologies for any grammar issues and/or bad explanations.
