I've mostly printed mine out walletsize too, easier to fit into the envelope! Although I never really thought of printing them on paper before! Will be sure to ask if that counts as an "extra page" at my pals places.

I was never sure what type to send either at first. I've sent a few now though, just face and top half shots pretty much.

I was just told to imagine that many people would see them, so make sure I was comfortable with whatever I sent being seen! Though, it strikes me that what is perfectly regular to me on the outside may also be seen differently in there.

I wish I could be a fly on the wall though sometimes when they get these photos! Especially if they pass them around!
