use a utility knife to peel up a piece of the border and slowly peel off the vinyl fronting with your fingers. then soak down the paper backing with a commercial wallpaper paste solvent such as DIF according to directions (the hotter the water the better) , let sit 15 min.,re-wet and scrape off paper backing using a dull (so as not to damage the drywall) scraper or hopefully your fingers. re-wet the paper backing often.
