I recently did a double sided board.  Since I usually post-process my
cad files to include a border around the board (to hold the TT paper
down), I simply put a via in each corner of the border, with a 13 mil
hole in it.  This is the size of my smallest drill bit.  I pre-drilled
the blank pcb for those holes, and poked holes in the TT for those
also.  I used the drill bits themselves to align the TT with the PCB,
then taped it down.  I was off by less than 10 mil.  Not sure what
I'll try next.  Another option is to do two single sided boards and
glue them back to back after etching.
