My decoupaged wall is one of the most talked about things in my house. It's tucked away in our guest bathroom. Everyone that visits comes out of the room for the first time with a huge smile on his or her face. The first question is always "did you do that yourself?" The second, "was it easy?"
I used two paperback copies of The Hobbit for my wall. I collect JRR Tolkien books and had about 12 different copies at the time. The two I used had damaged covers and the pages were already falling out, which is what originally inspired the project.
WARNING: This is a permanent application. Do not use this technique unless you are absolutely sure you want a permanent change.
Variations: Use maps, picture or art books, newspapers or letters
Read the label on the protective finish you've chosen. Follow all the warnings about proper ventilation and handling... I don't want you passing out while you're decoupaging!
protect floor, baseboards, etc, with newspaper or drop cloth and masking tape
gently remove the cover of book
peel apart the individual pages (this works best with paperback books and books that have been glued to their spine)
tape a large piece of parchment paper to the cardboard
wearing the latex gloves, put place several book pages on the parchment paper
using the paintbrush, cover each with Polycrylic
Start applying pages to the wall. For a neat effect, line pages up side by side, or overlap and vary (as shown) for a more staggered effect
"cut in" by placing pages side by side or slightly overlapping to frame your wall then working your way in
Use the brush to smooth out any air bubbles. You only have a minute or so to work with each page, so make sure you're happy with it before moving on
allow pages to dry and then apply another coat of Polycrylic over the wall
Use mineral oil and rags for clean up. Be sure to follow all manufacturer's safety instructions
