The only reason I'm bringing them up again (besides not having found something new to highlight this month), is because I only recently learned that you can now make a Pinterest page for your shop. Just go here, and your shop can have its very own Pinterest presence.
Not sure how to get started? They also have a board called "Getting Started on Pinterest".
Do you have a business Pinterest account? (Am I the last one to find out about this?) Let me know in the comments. I'm going to want to follow you.
