Here's a method that works really well for me. Print out your pattern onto paper, as per normal. Trim roughly around the template, leaving the actual lines with paper still surrounding them. I then take a regular glue stick for paper ( either UHU or PRIT will do ), and smear glue onto the back of the paper template. I then stick the paper onto the SINTRA or Styrene and smooth it out. After about a few seconds, I then cut out the pattern. I use my scroll saw, so I've got the lines that I can follow. Once you're finished, you can now peel the paper off and simply rub off any remaining residue.
