Apologies if this is mentioned elsewhere in the thread--it's huge (I've been reading through it for a couple days and I'm not even halfway through).
When I squeegee prints prior to hang-drying, they curl up like crazy. When I don't squeegee, they don't exactly dry flat, but pretty close. I'm thinking that my squeegee technique is lacking--perhaps I'm forcing water out of the center of the print, leaving more around the outside edge (or vice versa); thus uneven drying might result in curling. Also, when hang-drying, the bottom drys more slowly, thus stays slightly heavier throughout the drying.
This is just theory, but based on observation. Thoughts, anyone?
