I started selling on TeePublic a few months ago with zero experience. I uploaded 10–15 simple designs for t-shirts, mugs, and posters using Canva. Within three weeks, I made my first sale, and now I’m earning $50–$100 per month passively.
Biggest lessons: keep designs simple, focus on a niche, and use clear titles and tags. TeePublic handles printing, shipping, and customer service, so once your designs are up, it mostly runs on autopilot.
