Loris...thanks for the advice. My local art supply store has Masa paper and it is ridiculously inexpensive so it is worth a try also. If I printed bigger, I'd probably get a piece of plexiglass and tape the paper to it for development. I'd crease it for sure. Also, what is the downside of adding the citric acid? I think I'll try both with and without for my calibrations just out of curiosity.
