It's hard to tell from your blog, but do you use tags?
Do you follow people on there? You could reblog someone's post that you find fitting with your theme. I think there's one called "loveetsy" that accepts submissions of your Etsy items that they will feature.
You can include your link in your email signature, your etsy profile, your notice that buyers get after they place an order, and any social sites you use.
Perhaps include more writing in some of your posts because that would help people find your blog when they use the main search bar.
