Hey, don't care one way or another whether people sent my cards in an envelope or not. Just enjoy getting the cards. As far as drying a couple of fiberglass window screens and you good to go. And I process 6 at a time and just shuffle through the stack in the trays. I could do more but six is comfortable and I'm not in that big of a hurry. I always mail myself a card and it goes in the album with all the others so that I have a record of what I sent for that round.
