Keltia, one of my Celtic mermaid watercolor paintings is featured in this Treasury of Arts and Crafts on Etsy (third row down, in the middle.) If you want to help promote this Treasury just click on the Etsy link and then click on each image you see in the Treasury and leave a comment too!
I also discovered a very cool website that allows Etsy artists to find out if their art is featured in a Treasury - Craftopolis.
