With the door cracked open just a bit, to allow some air flow through the room, I lay them out on the mats for just a few minutes, to allow most of the moisture to fly out of the paper. If I left them like this much longer, they would crinkle up ... just a few minutes is enough. I then put them one by one between sheets of flat card for the final drying. They come out a couple of hours later perfectly dry and flat.
All that remains is to trim them to size in a paper cutter (the finished print has no visible white border), check them over, sign them, and then send them off to John, the coordinator for this Exchange.
Thanks for coming this far through all these photos! I hope it's been worthwhile ... And special thanks to my two daughters for 'coming running' every time I called for another photograph!
