Templates come in a variety of shapes and sizes and are save you
a great deal of time in precise drawing . Gun Muzzles, Car wheels..just
about anything. It also saves you from using a traditional compass
and punching holes in your paper. One problem though..They are
flat so ink can run underneath them and smear your drawing. Tape
pennies under the edges of the template to raise it from the surface
and avoid the ink smear.
