While  I'm at it.. has anyone got any tips for aligning the two transfers
for top  copper and bottom copper?



For onesy-twosy work, I just tape the negatives (transfers?)  together along 
two adjacent edges.  Assuming they are at least translucent,  and you can SEE 
the points you want to align.
 
I have heard SOME folks drill "spotting holes" or "targets"  before 
sensitizing the blanks, and with those, you can "lay down" the transfer  with those 
"spots" aligned.  Takes some planning!
 
Professional houses do it with  MONEY!!!!!!!!!!!
