Seven inches in a whole month! I didn't realize that Rochester was in a desert. An humectant is the last thing I need .
Thanks for the tip about little prints. If one were determined to enlarge, I think you could find 3 x 5 inches of flat paper on about any brand of good, mid-weight watercolor paper (except maybe commercial baryta - I'll check that out next time I coat it.) Fabriano Artistico HP would certainly work.
At this point, it's only fair to admit my bias toward contact printing. Nothing (to my eye) compares.
