There is a blog called All Things Handmade that has a "Mini Blog" where they post Etsy minis for Etsy sellers. They have categories to place minis in. Examples: Accessories, Art and Illustrations, Bath and Body, Candlemakers, etc. It is free to place your mini on their site.
They also have a links page where you can be added as long as you have a link to their site on your blog. The have buttons with code to use for linking to their blog.
The site is run by volunteers!
