Why not use maple as your wood?  I would try India ink myself.  You can =
buy it in quarts.

  Hi Mark and list,

  You've got it right, as to what I'm trying to achieve.  You are also =
right that poplar has almost no grain, which was why I selected it.  (I =
thought the finish I wanted would be completely smooth, but that would =
end up being too much work on a mass production basis.  What I noticed =
is that the light grain of the poplar actually doesn't look bad -- or =
wouldn't look bad if I could find the optimal finish.  I'll also be =
testing red oak for a coarser grain look.  This may ultimately be a =
better choice, albeit more expensive by about $2 per frame.  I'll be =
after a light sheen (satin).  I've tried the acrylic latex, BTW, and it =
just doesn't look right.

  As Joe said, it's an experimentation thingie, and I'm in the =
experimental stages.  I was simply hoping for some advice about =
lightfastness and did get some helpful tips off list.  (I'll reply to =
those shortly.)  Anyway, I've got enough to keep me busy for a while, =
and I thank y'all for the advice! :-)

  Peace,
  Sarah

       When I said I wanted to "show the grain," I was referring more to =
the thickness of the finish (i.e. texture) than the depth of the stain =
(i.e. color). =20

      OK... then if I understand you (maybe not) you want the wood =
completely black, as in opaque, but you want the surface of the film to =
show grain, as opposed to a grain-filled, perfectly flat surface.  =
Right?  Am I getting warm? ;-)

      If that is the case, it would seem the choice of poplar somewhat =
complicates achieving this desired result, despite its many virtuous =
qualities otherwise.  Poplar has virtually NO perceivable grain - well, =
VERY little - so whatever coating you put on there will have to be =
mighty thin to show any texture from the poplar.  Do you want a sheen of =
any kind, or flat, with no build?  Perhaps a water-based product will =
accentuate what grain there is by swelling the poplar a bit.  What about =
black acrylic latex paint - one coat, two coats tops, with the first one =
thinned a bit?

      Ya got me!
