"I wonder how hard that would be to take off and if the wall is in good shape behind it."
I reached up to the border and peeled back a piece. Easy peasy..... it was all good. I proceeded to pull more of the border off until I had it all gone. I then cleaned the wall behind it to remove the glue stickiness. I should have gone to bed at that point.
The amazing thing to me was that underneath that bottom wallpaper was gray paint. Gray paint? I didn't get it.
Despite the fact that it is going to really bug me to have that one layer of wallpaper underneath my new paint, I'm not about to tackle that long wall in the third photo. You can't see seams in it and it is pretty smooth, so I'm just going to paint over it.
But, I don't know if I'm amused or aggravated about the gray primer!
