Over the past several years I have told my students about a compass I use. The compass point and pencil point are two separate pieces that attach to a 1″ x 12″ Onmigrid ruler or you could attach them to a yardstick. I usually don’t need to draw circles any larger than what my 1″ x 12″ Omnigrid ruler allows but if you needed to draw a larger circle you could attach these points to your yardstick. It allows me to draw perfect circles, which is a shape I often use in my designs. On my website, under “Tools for Designing” you will find both the 1″ x 12″ Omnigrid ruler and the Yardstick Compass. I love tools that make my life a little easier.
