Silly me. For some reason I was still under 
the impression that the lines were on the top 
of the acetate and the paint was on the other 
side. I think that's how they used to do it back 
when lines were hand-inked? Well, ah, I'm 
sure someone did it that way. I just realized 
you're right though 'cause sometimes when 
pencil sketches get stuck some of the line 
powder will come off on the sketch. Bummer! I 
wonder why they DON'T photocopy the lines to 
the front though...
