Cover the Top Edge of the Roombox with Paper To create a strong, neat lining for your book board dolls house roombox, cut a small triangular piece out of the top edge of your lining paper, almost, but not quite to each of the back corners. See the photo for details. Carefully apply glue inside this paper edge, and fold the paper over the top edge of the roombox to the outside. Use the bone folder to smooth it in place.
