Question: The paintings I had photographed and made into a note card measure 5 1/2 " square, and my concern is about fitting it into a 5 1/2 square envelope. Would I want to go up to 6x6 or is there room to spare so that the cards would fit?
Answer: The Envelope size you will need is at least 5 3/4 X 5 3/4 (not an easy to find size). You can use a 6 X 6 envelope, however there will be extra room; if at all possible, increase the card to 5 3/4 x 5 3/4
