Someone else posted this, but, These were the measurements I also used for the Christmas Card I made in 2012--Used a beautiful snowflake set from SU 1995 and Season's Greetings from another old SU set. Would like to use a set with leaves sometime for fall cards. Posting in case I lose my own Cheat sheet that I got from an SU demo.
Lovely As A Tree by Stampin Up. I really love, love, love this card. It's not hard to make either. For instructions on how to make it go to http://thescrappingqueen.blogspot.com/2014/11/samping-on-vellum.html
