That is such a good idea! scrapbook paper. I bet you could use wrapping paper too. I have wall papered a lot, just not in a dollhouse. I think wallpaper paste is a good idea because it gives you time to move it. You can buy it in powdered form and just mix as much as you need. The ready made would be way too much. I would use a basting brush and apply it to the paper and then slide into position. Cut it a tiny bit too big and then when the paper dries on the wall trim it with a pen knife...because it can shrink from wet to dry. You should post picts when done.  If you want post one here Stained Glass Obsession I'd love to see.....maybe you could even add stained glass windows. That would be cute.

Ditto the mod podge! Just spread a thin layer on the wall, lay the paper on top, and use a credit card or the like to smooth out air bubbles.
