Of the leathers, green and browns are the most popular, though almost any color may be obtained. Make full size drawings of the outline and design of the fixtures.

With a small metal saw cut out these parts and smooth up the edges, rounding them slightly so they will not cut the leather or silk. Next cut out the outlines with the metal shears.

In the design shown, the unshaded parts should not be etched and should, therefore, be covered the same as the back.
