I recieved an email in May about winning the gift certificate from the March shophop. I think it depends on which shop site you win from, as to when you get notified. But they post the big winners around the 15th of the following month on the shophop web site. I'll check again...but I believe that's what it says in the members area.
Yep just went back in my records, I received my gift certificate the 15th of May for the March shop hop. Received my fabric on the 21st.
