"Got to market it."
Yes, I agree. If an artist/designer wants to sell his or her artworks/designs or merchandise featuring his or her works through PoD sites, they have to market it. They have to promote their stuff. That's why I promote my stuff on places like my "Richard H. Fay - Artist" Facebook page:
And my Azure Lion Productions Pinterest profile:
And my Richard H. Fay Twitter account:
And, for what it's worth, my Azure Lion Productions Tumblr blog:
I even promote here, on my Azure Lion Productions Blogger blog.
I also promoted my stuff on Google+, but Google sent me a warning claiming I was spamming. After that, I closed my Google+ account.
I even posted some stuff on StumbleUpon, but I haven't posted anything new there in quite a while now.
I'm always working at getting my stuff out there and getting it seen. I do understand the importance of marketing and self-promotion. Having a distinctive style that stands out from the rest certainly helps. However, I think the most important thing of all is to have artworks and designs people like on items people want to buy. Everything else is ancillary.
