For the past several years, the t-shirt market, or rather the market for selling t-shirts online, has been exceedingly hot. Just Google "T-Shirt Success Story" and you'll find example after example of people who've started a successful t-shirt marketing business on literally nothing. Many of these people now have steady five figure monthly incomes all based on selling well-designed t-shirts. Obviously, this is of interest to anyone who wants to break out of the nine to five employment world.
