I'll be doing that this weekend!  I have three full days free. Neg is 
printed and ready to expose.  I will powder everything but my tushy.  My 
biggest problem is figuring out how to see through the screen to expose the 
strips in equal increments...

My screen I used to always use was Dan Welden's but I bought the Elizabeth 
Dove one.  It is reallllly nice-more sturdy, etc.

Yes, PDN is as simple as it is complex.  If I can teach it to 17 students at 
once and they all see the value in it (with a couple slackers who don't want 
to put the time in and pay their dues), that is quite satisfying.  We are 
doing platinum these next two weeks, but even VDB was astonishing in how 
beautiful it was, especially on Weston paper, when curved right.  With gum I 
had them do uncurved negs first and then curved negs next to compare the 
difference--same print.  That is always a great visual to students when you 
print an uncurved and curved side by side of the same exact image.

More than all that, it is the beauty of seeing how different materials 
respond to different colored light--solarplate requiring more of a blue 
range neg which would not work in many other processes. I'd still love to 
know the hardening chemical in the plates.
