Wow, thanks! That's a lot of wonderfully useful stuff! Ironbear, I had read your tutorial on RDNA... it's what got me into the sketch designer in the first place. I love playing with blended layers in Photoshop-- I love to muck about with the same image and many different filters on many layers, just to see what happens, so your tutorial is very interesting to me. So far I have found that if you turn the outlines completely off, either by setting their density or their opacity to zero, you don't get inside-the-head lines, but then you don't get any outlines at all either. There has to be a way, I'm sure there must be a way... I'm very grateful for your help, and if I find anything, you can be certain I'll post it. Don, thank you very much, I've downloaded your .pdf and shall have a look tonight!
