How do you present (hand over) your photo cards/thankyous and announcements? I was thinking of getting a nice envelope at Staples, and just having them all in there? What size do you make them? I made the mistake of offering 4x6's to keep things cheaper for some customers, but now I cannot get matching envelopes!?! Staples does not even carry the A6 (4 3/4 x 6 1/2) size. Anyone know where I can get some or have any other suggestions? Guess I will stick with the 5x6 or 5x7 from now on!?
