Centigrade, be careful squeezing leather punch cutters, do it slowly ,and dont go to far. If you over do it the cutter can split. I would also recommend using bit of card or thick paper underneath whatever foil you're using when punching out,this gives a cleaner cut. Like i said ,I just used what happened to be lying about to get an idea of the look, and to test the application process. If i can help with this,let me know. Once i am rid of flu I plan on taking it further ,with different foils and effects. Regards.........glider
