I am in love with trifolds!!  These are folded in on both sides to create 3 sections of a 5x5, as well as printed on the front and back.  Opened, it measures 15x5 inches. For Halloween, these trifolds and any card are great on PEARL paper!

 You can substitute envelopes for a 5x7 to save on postage.  5x5 needs extra postage!!
