Homebrew PCBs

i ask because i'm not sure how a foil would react in a laser printer. i'm using the printer on my desk at work. i forgot to tape a thin magazine page to a regular sheet a few days ago and had to pull little pieces out of the printer. fortunately i was able to get them all and didn't have to call the help desk to explain what i did it. i'm going to give this some more thought before i try it.

thanks!
