This specific wall is difficult to place right now and needs wallpaper and a lighting fixture.

The beads come together to form a sconce.
This dollhouse appears to be half scale, at least that's my impression. The listings for these kits often do not specify their scale, and when they do, it is usually incorrect. Use a glue stick to attach your wallpaper, as mucilage can be tricky to handle at this smaller size. You want to avoid oversaturating your paper with too much moisture.
