Lesson 6 brings us to a new shape, the square cushion, and a new style, the checkerboard. Deep checkerboards show off color and clarity, while shallow ones lighten dark rough. This lesson teaches how to cut multiple facets out of a single meetpoint (P4), and how to cut a checkerboard crown (C3 - T). Lesson rules: cut in aquamarine, with no size restrictions
