Drew these on 90 lb. paper because I thought I'd go in with one wash and stop ... Of course, that's not what happened, and the washes got tired looking, which seems to happen quicker on lighter weight papers.
So, I'll consider these preliminaries and redraw them on 140 lb.
A few people asked, in comments on the previous post about too-absorbent paper, what paper I was using. I have a stockpile of paper, most of it Fabriano, some Arches, 140 lb., in sheets and blocks.
I don't know what causes the problem--where the paint sinks in instead of remaining on the surface for a bit ... It's very humid here at the Jersey shore, and I think that's probably the culprit.
I try to keep my papers, even in the block, covered (so I won't take a painting off the block until I'm going to start a new one), and I think that helps.
