These models are suitable for historical, fantasy and dark future settings. They are designed to be easy to print and assemble, each of the eight L-shaped corner ruins pieces requiring at most two sheets of matte photo paper to print on. You'll also need some common hobby supplies including scissors, a hobby knife, cutting mat, cork-backed metal ruler, glue stick, and paper glue. For best results, black felt-tipped markers and some basing material such as cereal box cardboard are recommended. Illustrated step-by-step instructions are included.
