Decorating with wallpaper is a trend in home decor that comes and goes. Currently it doesn't seem to be a popular fad in decorating homes in America, but every so often a new 'look' comes out that everyone wants and it rears it's head again briefly.
Something our mothers and grandmothers did was make their own wallpaper paste to use to 'glue' it to the wall. While the industry came out with pre-pasted paper, many have found the thin layer of built in paste is not sufficient or is of such poor quality, that the paper does not adhere to the wall. Especially if it is covering paint that had a sheen to it, as in a bathroom.
I found a couple recipes for homemade wallpaper paste a few years ago and I believe I may have post one at the time. This morning I'm going through some old files and saw this one from 07'. I guess it's been sitting there long enough! If you need wallpaper paste, here it is. I've never used it personally, as I'm not a fan of wallpaper, but it deserves to live outside of my files and see the light of day!
Homemade Wallpaper Paste
1 1/2 cups white flour
1/2 cup sugar
1 tbsp alum
1 cup cold water
2 cups boiling water
Combine flour and sugar. Slowly add cold water and beat/mix out any lumps. Put mixture in a saucepan over a medium heat. Add the boiling water, and stirring constantly, bring the mixture to a boil. When stiff, remove from heat and add alum.
