Thanks to the internet and the sites mentioned below, you don’t have to be a famous designer to put your stamp on products. Anyone, and I mean anyone, can earn money with this.
All you need to do is sign up with a site like CafePress, upload a design you have created, decide which items you want the design to go on (i.e. T-shirts, hats, mugs, etc), and make money selling them.
The best part about this is that you don’t even have to ever touch the actual product, nor do you have to spend a dime on manufacturing these products. They do all the work for you. You just upload the design, choose the items you want your design to be on, and they’ll handle the rest (i.e. manufacturing, payment, shipping and handling, returns…).
