I'm sure everyone has a Facebook page to link to their Etsy shop, one thing that might be worth trying is promoting to friends of friends by getting them to get their friends to Like your page. Try offering a free gift to the person who gets the most likes to your page, have them post their name on the wall of your page, once you do this when you post your updates on new items, sales, etc you might get more traffic to your shop. Just an idea......
