what i've been fiddling with so much these last few months is seeing how much i can leave out while drawing a face and yet still have an expression, a feeling, come through. i try different colors so i can see what their effect is. each little change makes a difference, and usually a big one. a face can go from happy to sad with one dark pencil stroke.
since the first 'face book' i've been letting what's already on the page show me where to start. there are usually blobs of walnut ink or wrinkles that point the way - a face is in there somewhere.
i drew/colored 'della' this morning while having coffee - i have to make myself not fill everything in; leave some mystery.
plaster cloth can be found at michaels for about $10, and jude's got a great post here about collaboration and 'diluting our efforts'.
