Love Serenity! I just used it here:http://adcausetreatment.blogspot.comI also installed your button in my sidebar.
Hope you're doing well. Miss your backgrounds. Came looking to replace my last one with a new autumn inspired one. Can't wait for what else you have up your sleeve! Yours (with the 3-column formats and the accompanying headers) are the best I've found! Thanks for offering them for free! :)
