Long ago, I've done drill-first with just the basic Radio Shack PCB
kit, it works just fine. Simply print out your pattern on a piece
of paper and tape it to the board, then use a sharp center punch to
mark the hole locations in the copper through the paper. Now remove
the paper, drill the holes, clean off any burrs, and use your resist
pen to copy the printed pattern to the board. Same thing could be
done with TT, using your drilled holes to align the pattern before
attaching it for transfer.
