How to draw natural history specimens

In this segment from the 1980s Australian television program Curiosity Show, the host shows you how to make accurate drawings of natural history specimens using graph paper. You place the specimen (in this case, a spider) on a piece of graph paper. Then you use another sheet of graph paper to draw the spider, using the grids as a guide. You can use enlarged graph paper to make a larger-than-life drawing of the specimen, as the host does here.
