The easiest way to avoid wrinkles, other than ur suggestion, is to mark one end on the paper where the vinyl should go, cut a 1/2" or so strip of the vinyl paper backing off the one end, then lay the 1/2" exposed vinyl over your marks, use a flat surface to smooth the vinyl down as you slowly pull the vinyl paper backing off.

You will need to be careful you don't wrinkle the vinyl when sticking it to the paper before running it through your laser printer. I slowly start at one end and apply the vinyl to the paper at the same time I'm peeling off the backing of the Oracal. Three hands would help here! Once it's stuck to the paper, you will never get it off to smooth out any wrinkles so u must make sure there are NO wrinkles in the first place! Order a lighter colour of your Oracal. I use a bright yellow although the blue that's shown in the Youtube video works too. There is a transparent version available too but the "Vinyl Direct" company doesn't stock it. The transparent version would help when making double-sided boards. I've been told that this Oracal 651 product is used a lot by sign companies so scraps of it may be had for free from one of these shops. Anyway, let us know how this works for you.
