We cut it all out of felt and stuck it to the door with removable poster tape. I found the idea on this blog- http://www.pepperdesignblog.com/2012/10/30/pinterest-challenge-christmas-comes-a-little-early-this-year/
Cameron loves pulling the ornaments and lights off and putting them back on. (And pulling the whole thing off the door.... But we're working on that!)
It's really nice to have a tree that we don't have to worry about being destroyed! Now it feels a little more like Christmas around here!
