It can be found almost anywhere, and can be used for just about anything. The fact that it can be found almost anywhere is a valuable asset all in itself. Shoot on down to Longs and get a roll of scottish plaid. It's untraditional, but it works. Let me tell you now before you go and give yourself a headache.
Contact paper is designed with a rather gunky kind of glue.
It's not so bad when you apply the tape, use it on glass, then remove it all in the same day or two. But when you leave it on for a few days before you take it off, it tends to equalize where it wants to reside. So when you go to remove the tape, some of the glue decides it would rather adhere to the glass instead of where it came from. What this means is that if you are cutting intricate designs into the contact paper, and don't pull them right away, after a while, some of the glue will remain on the glass. This can cause real problems.
