Step-by-step instructions - How to put Contact onto school books with no bubbles and no tears!

I work in a school library, so I cover books for a living. I have found this method to be the easiest, and most pain-free way to get those books covered in adhesive plastic Contact. All you need is some good quality adhesive plastic Contact, some sharp (clean!) scissors and a ruler, or similar. Scissors can be cleaned with Eucalyptus oil, De-Solve It, or other sticky residue remover.
