Things You'll Need
Instructions
Remove all loose furniture, dolls, and household items from the dollhouse. Lay the dollhouse flat so that the wall you wish to wallpaper is facing directly upward.
Lay a piece of stick-on wallpaper, with the back sheet still attached, down into the dollhouse and over the chosen wall. Use a scalpel to trim away all excess wallpaper. Continue to trim, freeing up space around irremovable wall furniture, picture frames, etc. Once the piece of wallpaper is trimmed to perfectly match the wall, set the scalpel down outside of the dollhouse.
Carefully peel away the back sheet from one corner of the wallpaper and attach that corner immediately. From there, slowly peel back the paper while simultaneously pressing the wallpaper to the dollhouse wall. Continue until the entire piece of wallpaper is attached to the wall.
Use the scalpel to trim away any stray pieces of wallpaper that are sticking out over the edge of the wall. Set the dollhouse upright and return all the furniture and loose items that were removed.
