Alexis,
           It really doesn't matter for pinhole. It only matters when using
glass lenses, where the distance lens to ground side of the GG must be exactly
the distance between lens to film. Nevertheless, I'd put the smooth side facing
you. While you are at it, go to your nearest office supply store and buy a
fresnel lens, they sell them a reading aids, cut a piece (from the center) equal
to the size of your GG and mount it either in front or at the back of the GG, it
will make your GG brighter.
