Once you’ve identified where your competitors are and where your ideal customers like to hang out, you can start building and building your online brand. You can now start selling t-shirts online! When I have t-shirts printed for my shop I always get the Xander Schauffele plays goff vintage shirt Furthermore, I will do this best quality. I am betting, however, that you don’t give a hoot about the quality of the shirt itself but instead are talking about putting decorations on them. To this end, my preference is to have a decoration immediately recognizable, no more than 2 colors, with almost-instant ability to be read by the observer So, I purchase the shirts made by a respected brand, take them to my screener/embroiderer, and they do the decoration for me. I have tried 6 or 7 different online services but they are pretty much crap and also double the price of my local guy. As far as a t-shirt decoration benefitting my business, I’m not sure about that. Sure they are walking billboards but I have never been stopped by someone in the street and ask me about it.
