My work is non line at facebook, RedBubble, MySoti, ArtWanted, another one I've temporarily forgotten, and not least, my own website at www.matelles-art.com. If you look up artists websites on google, you can see the incredible number of 'websites for artists' - some offering 'free' sites (some advertising) some asking for money to host your information. It's a complete mess for all artists, and for anyone looking to find an artist of their work.
My personal favourite is RedBubble, because it's free (they'll sell your work and take a cut), and because it's simple to use. Uploading your work is easy, and it looks good. MySoti is a pain because it is harder to upload (and really they're a T shirt site) and their ability to supply promptly is not good, artwanted want an annual fee AND it's hard to upload..
So I took a look at 'Writers and Artists' and found there's EVEN more than I thought. Look out for my next new website - might as well upload everywhere!
