My method is mesh on fields and paper in corners. You get a much more
defined corner with paper. I use a corner trowel to set the tape; mesh
could never make as straight a line as paper, I think. And its easier
to avoid bubbles in corners, since, with a corner trowel, all the air
is being pushed out each side of the fold. Try it using about 5 feet
at a time, no banjo, just a corner trowel. Overlap the next section and
continue that way around room. If you've ever had problems in corners
with the mesh being exposed after sanding, you'll appreciate the ease
of a sanding block over a straight paper corner.
