My very first card was a pop up cube in an envelope. This was a great resource. I loved this instructional video! http://www.youtube.com/watch?v=ZHir04ChSHw&list=PLDC547F092783608A I found this to be a fantastic for a Thank You card/envelope combination. After a recent trip I thanked two of my relatives by making each of them one of these as a “thank you’ for hosting us during our travels.
