Need to draw a really big circle? Need to bisect a really big angle? just add two of these to your yardstick and presto! huge compass! The best yardstick to use is an old wooden one, then you can fix the endpoints with a tack or small screw. The hole is perfect for a sharpie marker or a large drywall anchor (to hold sculpting tools) if you have a suction cup you can draw large circles on glass too. Lets see if this will work with customizer.
