Psst, Anna, you know we have a Foundations Flickr account, right? I suggest starting a new Collection called 1908 Corset Sewalong, Summer 2013, and you can have as many Sets as you want within that.
I'll let you have the login details by email.

Also, I agree about Pinterest but for different reasons - we decided to withdraw from using it because of the copyright scare. As a small business as opposed to an individual, we're an easy target for those seeking a payout.
