LizBeth91 : I have never put wallpaper over wallpaper. Didn't know that was possible not that I would have ever done that. When we moved into our house in OH in 1993 there was a wall covering in the bathroom and also the kitchen. It was a heavy paper(?) and also had strings in it. I took it off the bathroom but after doing that I painted over the kitchen. It was horrible taking the "stuff" off that small space I would never tackled a large kitchen/dining area. The paste was about 1/8 in thick and horrible to remove. I used to like to paint and wallpaper but too old now.
@Nuisance : It's been about 5 years and I think I might still do the same but I'm like you, gotten a bit older and wiser.
I think what drove me nuts enough to do it is that the walls had a crinkled texture and the color was kind of a dull beige-avocado. It was a weird puky color ðŸ˜
