Morton Circle and Border System (CBS1)
Product Description

The Circle & Border System is a jig tool for the glass crafter who wants much more than a circle for their plate and bowl designs. This unit is made up of over 20 bits and pieces - templates, rulers, blocks, even a screwdriver -- as well as a computer program and video instruction to help you figure it all out.
It is designed to be used with any one of the Morton Cutting Surfaces (not included). Note: When they say "border", they mean curved borders. This contraption does not help you cut straight borders.
