Laser cut note book with quotes

Me and my colleague wanted to make some note books with lasercut quotes on it. At first we wanted to see what it would look like when the laser cut all the way trough the booklet. But this didn't work out, because it took the laser too much power and the booklet could caught fire.

Then we decided that it would also be cool to just cut a couple of pages. To achieve this, we were advised to put some aluminum foil behind the pages. The laser can't cut through metal and this way the quotes will have a nice and clean look without any burning marks etc.
