There are two great groups of International Miniaturists and Doll Artists of which I am a member. Whether a collector or artist of miniatures, you might want to take a few minutes of your time to visit each one and see the awesome handmade miniatures my fellow group members have created.
These two groups are:
CDHM (Custom Dolls, Houses & Miniatures)
Etsy TeamMIDS (Miniatures In Dollhouse Scale)
CDHM has an online Gallery where members can choose to sell and/or market their creations: http://www.cdhm.org/ (click on 'Search Miniature Gallery') - this is where you can view some wonderful dollhouse miniatures. CDHM has a great online monthly magazine, "The Miniature Way": http://www.cdhm.org/news/newsletter0210.php They also have a blog: http://www.mycdhm.com/
TeamMIDS is an Etsy (sales venue) group of shops owned by individual Team members. TeamMIDS has a blog: http://teammids.blogspot.com/ ; a website: http://teammidsdollhouseminiatures.goods.officelive.com/default.aspx ; and a Flickr Pool: http://www.flickr.com/groups/mids/
