Another thing to try is to tape *three* corners, not two.  The extra
tension helps hold the seam centered on the thickness of the board.
Not that I've ever done that; my TT paper is too opaque to line up
that way.  I've pre-drilled target holes in the PCB and poked matching
holes in the TT paper to tack it down in the right place, with some
success.
