text: what is the proper way to put a greeting card inside an envelope? does the front of the card show or does the back of the card show when you open the back flap? the correct way is to hold the card in your right hand  with the front facing up as if you were going to read it yourself.  then slide it into the envelope.  the opening will be at the top.  then when it is opened, the person slides the card out and it is ready to open and read.  if you do it any other way, the card will be backwards or upside down.
