When I feel like it! This year I was going to start decorating the week of Dec. 11th. DH had other ideas, and had a heart attack that day!! (Pay attention to those warning signs!) He's much improved now, but we got sidetracked with surgery, and a hospital stay. My son came over and we decorated just in time for DH to come home. I usually don't take it down to mid January. This year I want to purge a little more. So many things I don't use anymore.
