Homebrew PCBs

Hi, what is your "technique" to properlu align double-face boards? I am 
using toner transfer and a laminator. So far thge best method I've found is:

1) print out the two faces on special paper. Make some holes in 
reference points, I use the mounting holes.
2) put only one "face" in the laminator with the board and pass it a 
couple of times until it is fully "attached".
3) wait for it to cool down
4) drill holes in the PCB using the holes in the paper as reference
5) align the second face on the back and put it in the laminator, and 
pass it several times

6) proceed with removal and etching etc

Do you have any advice?
bye
