Recently, I posted about a print on demand service called Society6. If you missed it, you can find it here: Society6 Review
At Society6, members can not only sell prints of artwork and design, but also sell them on products such as ipod cases, laptops, t-shirts, hoodies, pillows, and more. Society6 is basically an opportunity to license your art for printing on products (though Society6 does not assume any ownership of the works).
I have posted a few products for sale and am enjoying my experience with Society6 thus far. I haven’t sold anything yet through the site (only been there a week), but wasn’t really expecting to yet.
