Selling T-shirts and other apparel is a pretty saturated market but the tools to do it are easy to use, which makes it very quick and cheap to get going. If you’re creative enough, or tap into the zeitgeist properly, you can also have a runaway hit. Even if your first 19 T-shirts don’t sell more than a few copies, your 20th might make up for everything.
