Homebrew PCBs

What do you mean by "some succes" ? Is-it often, 3 out of 5, or less ?
Is there a big off-registration ?

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.
