Anyone have experience selling shirts on Teespring? I'm fairly proficient at Photoshop, so instead of purchasing a design off of Fiverr, I made my own designs. The marketing part doesn't seem too bad; it's mainly hit and miss, depending on how well you connect with your audience. Which audience has been most profitable to you? Which demographic is most likely to purchase a shirt? Anyone have any tips for someone that's starting to get into making some extra money selling shirts?
