The interior of the Crypt module is finished, but the sides and the top are still quite unsightly. Raw extruded polystyrene, even with a coat of grey paint, does not look the part.
Part I of this tutorial focused on the basic layout of the Crypt, Part II focused on vegetation (vines, moss, mushrooms and roots) and Part III on all the man-made details (skeletons for the alcoves, urns, candles and sacrificial offerings).
In this part we will use black styrene sheet (commonly known as plastic card) and black, self adhesive vinyl film to add a sturdy and visually pleasing finish to the sides and bottom. We will also make the top more appealing in adding a rock texture that matches the walls of the crypt. First I will point out some problems that came up during the construction process and possible solutions for them. We then proceed to a list of materials used followed by detailed step-by-step instructions.
