Today, I came across a new site called The Mixed Media Art Directory. Here's a description from the site's home page:
"The Mixed Media Art Directory is an all-encompassing directory for links related to mixed-media: art and artists, shops and supplies, methods and mediums, blogs and Web sites. Find your favorite artists, or discover new ones! If you care to register, you'll even be able to keep a list of all your favorite links!"
The site is still in the growing stage but there's a lot to see. Check it out!
