Anyways, I've read that people send out index cards as well, even customizing them, whcih sounds like a good idea. When it comes to sending photos, what are your preferences and why? I was thinking that for the autographs that I really want to have and show (framed), I am going to send 8x10's. Everything else 5x7s. Save money on postage too

What are your preferences? Do any of you do 4x6's?
Thanks in advance.
