Lady Adelicia de Clare of Atenveldt has set up a Facebook Page dedicated to sharing "thoughts, patterns, ideas, pics and sudden brainstorms without judgment." It has an international membership, lots of great photos, and some pretty knowledgeable folks who don't mind having their brains picked by the rest of us.
If this link doesn't work for you, just log into FB and search for "Persian clothiers." It will pop right up. Then, to join, click Join Group in the upper-right corner of the group's page.
