I checked back through my notes, and Summer was attacked in July of 2010. Since then, Summer has been very active in our team, and loves to make treasuries! As a matter of fact, being attacked was what decided her to join our team!
The first time that Summer sponsored a sneak attack was about two years ago. And she has sponsored several times since then.
I went browsing through her shop this morning - I love all the earrings that Summer makes, as I've an obsession about earrings - but I guess you know that :D
And boy, did I find a wondrous pair!
