Borders an wall paper have been problems for everyone at times. When Mfg's peel off I will replace with a more decorative border an I will use a good "vinyl" glue that comes in a tube, to prepaste the border. you will roll it out an remove excess with wet sponge. Home Depot or wall paper store will have the glue.
While your at HD they have brass back plates to put behind your draw an cabinet handles so you Lady's do not scratch the finish off cabinet door with your long finger nails, you can save them for Hubby.
If you put on plates pick up some longer screws, plates cost about $2, better than the ones I got at Newmar.
Also I never liked the plastic towel racks, toilet paper dispenser, I have brass bath faucets so I got new brass hooks,rings,towel racks an dispensers, have two baths.
Pictures yes we have them young children, birds, landscape scenes, grand kids, hung up with nails an velcro strips. Put a nail in wrong place, plug up hole with wax crayon will never see the hole. Thomas Kincade wall clock, you change the four seasons scenes, reminds me have to change to spring scene.
I have also added window sills for all my wifes collectables.
If you really want to get into something install a DVD surround sys. but thats for another project. Have fun fixin.---"007"
