Print On Demand...
Print On Demand services are a great way to get customized, even one of a kind, products without the cost of totally custom work. These services have a variety (sometimes large variety) of products that are printable. You supply the image to print on the product and some weeks later it shows up at your door. Yes, often a bit pricey if you're comparing to WalMart and other discount stores. But, consider what you get: products that are you and that you won't see on anyone else.
POD services are great for the individual with some artistic leanings. But, they are wonderful for designers and artists who want to sell their work. No longer must a designer/artist commit to canvas and convince a gallery to show and sell their work. Now, the artist can create digital work or digitize physical work, upload to the POD, select products for printing, and make their work available for the world.
This can produce a passive income for some or be an on-going side business for others. Rarely, this can make a living.
