I'm doing the faceup on Jareth 2.0 myself. I'll have no problem with the eyes; those shapes are pretty flat, so they're easy to deal with. I will, however, have problems with all the nooks and crannies of the mouth. I hate painting mouths.

I've decided to go for the "nude lips" look, in which the lips are exactly the same or almost the same color as the surrounding skin, differentiated mainly by high gloss varnish. I thought it might be as easy as just glossing the lip area repeatedly until it really shone, but I asked Andrea, more experienced in doll painting, if she had any tips. She said:

"Put lots of high gloss varnish on it!  Oh, wait…  Another thing I've done is to use paint that's almost the same color as the skin.  John (kd_230692) will paint the lips, then wipe away all but the paint that's deepest in the line between the lips (usually he'll do that because he's not happy with the lips he painted, then likes the look of the line alone…)

"I've also used a bit of pastel on the lips, then glossed over that (but I've done that only once, for Gretchen here http://www.flickr.com/photos/dollsahoy/6076359350/  –a color closer to the skin tone would make the effect more subtle, of course. )"

I think I'm going with the paint-and-wipe effect. It ends up looking pretty good, actually.
