Our most highly recommended print on demand site is Zazzle because it’s totally free to join and there is no restrictions on the number of items you can create, the minimum payout threshold is reasonable, payouts are timely and the sheer number of products you can put your designs on keeps growing. It’s already way more than than the other sites on this list.
Two other popular, totally free to join and start making / selling print on demand sites are Society6 and RedBubble. Although we do put content up on them, its not as much as Zazzle (Banner above) or Fine Art America (banner) below.
Fine Art America’s free membership puts a restriction on the number of works you can market on the site. The paid membership offers much much more. We have the paid membership and although we haven’t. The forum groups are lively and there are lots of different groups catering to the plethora of art genres. Have an in depth look at this site.
