Here is what I do.
Make print on regular printer paper of the drill pattern
glue it to pc brd with fabric adhesive ( sewing shop )
drill the four corners with a small drill ( mounting holes )
I usually drill all my holes ( your choice )
remove paper and clean the brd.
make print of artwork top and bottom
place them back to back ( align carefully by looking thru the paper with a
good light behind them.
put a pin thu one of the holes.I use a pin to mount a carnation in you
lapel.It has a plastic ball on the end for easy handling.The corner holes
should be close to the size of pin used.I place the artwork on rigid
styrofoam it gives room for the pins to pass.Both top and bottom also the pc
brd now have registration marks ( holes )
Pass the pin thru paper top side and thru the pcb and foam.After all the
pins are in I use an iron just to tack toner paper to the brd. If the brd is
small remove one pin.Flip brd and do the same.I fold a piece of printer
paper in half ,place the brd in the fold and pass thru a laminator several
times.Redrill corner holes for mounting to suit your hardware
