I pin the tissue to cardboard sheets and stand them up in my darkroom sink. I leave a fan blowing air on them for about 12 hours until dry to the touch. I then put them in black plastic bags that are the paper bags leftover from 11x14 silver paper that I've fixed out. I store the tissue flat under my pouring table with some light weight on them. Hope this helps.
How do you go about drying the tissue to keep it flat?
