hi dr.phil - i just used some crane 90 from photographer formulary for cyanotypes and agree with don, the paper doesn't like to be handled much. i was using a blow dryer, low setting, with an 11x14 sheet and tore the corner i had clamped to my drying line. i also noticed that i was rubbing off the paper fibers where my hand was holding the paper. the other two prints i air dried only after washing look great.
