In the case of the cost of building miniatures, every model maker retains a backlog of knowledge of found objects and how they can be ultilised for a model that of course keeps the costs down. Mary MacLachlan, a Weta Workshop miniature builder, explains in The Two Towers The Appendices, part of a series of documentaries on the making of the Lord of the Rings trilogy, that ping pong balls make great domed roofs when cut in half, and that the insides of spiced herbal tea bags look exactly like leaf litter. David Neat, a model maker, tells us on his blog davidneat.wordpress.com, how doilies can make great architectural details. The spontaneity and happy coincidence of finding and using everyday materials is something I took on for my own miniature build. I used wire brushes to achieve the texture of the rock for the bridge, alongside a hand made tool for the brickwork. To achieve the rock face itself required nothing more than a kitchen knife to carve the insulation foam sourced from the local builders merchants. My own project proves that with minimal equipment and budget something tactile and real can be achieved.
