This wonderful world is crafted primarily in 30pt chipboard with some wooden and natural material accents. Each original design is individually cut out, painted, decorated, assembled, and landscaped completely by hand. I design doors, windows and other printed accents on my computer and print on paper. The pieces can be illuminated by placing a small LED or other low temperature light through the access hole in the back of each structure. But care must be taken as each piece is made of primarily of chipboard and paper.
