Clara I've seen your work before (I think when your quilts hit the TQS gallery!) and only WISH I could be a customer! they're beautiful, and my little Curious George (age 10) is a quilter AND equestrian, he'd love it-- actually, he's seen them here too and wants one...
Anyway, I think one key to success on the internet is getting your site to rise to the top on searches. Wish I could tell you how to do it, but there IS a way, I just don't know it. You want to show up if someone is just looking for "horse art" or "equestrian art" b/c they may not be thinking of a quilt, but your work could easily win someone over!! Also "horse gifts" etc.
Also, from looking around your site, you may want to consolidate some of the info... for instance, the price and size don't show on your quilts for sale. Anything that makes it difficult for the user is a barrier. Even down to the purchasing, you've got the Ebay thing going w/ the photography, expand that to the quilts. I do love the style of your site
If you can advertise, target, target, target. Maybe a horse magazine has a classified section where you could try a small ad & see if that works. And remember, advertising is not an expense, it's a revenue-generator!
Good luck with this, I certainly hope any quilter trying to make a living out of it is successful, but You've really got something special here.
