So you want to design and sell your own t-shirts by starting up a t-shirt shop. There are many website choices out there, such as Spreadshirt.com, CafePress.com, and a few smaller companies. After doing some research on these you will find that Spreadshirt.com is the way to go. If you go ahead and get a domain name and hosting through www.1and1.com, you can get a Premium shop at Spreadshirt.com for a year. Spreadshirt also offers many features and products that are far superior to CafPress.com and other design your own t-shirt companies. With Spreadshirt.com you can get a flash t-shirt designer shop where customers can create their own products and Apparel. They also offer product brands like American Apparel that the others do not.  Spreadshirt.com also offers many different ways of printing including Flex and Flock Printing, CafePress.com only offers digital direct. I have also found that the products I bought from Spreadshirt.com are far superior to CafePress.com. If you want to check them both out I suggest starting with a free shop with both companies.
