Circle Acrylic Ruler 6"

Finally, a ruler that actually does circles without slipping. The anchor point holds the awl perfectly steady while I rotate it around—way more precise than a compass.

I kept fumbling with compasses for ages, but this ruler finally made drawing a perfect 3-inch arc take about ten seconds. The clear acrylic lets me see my fabric markings underneath, and the ¼" anchor hole holds the awl steady without any slipping.

I've been using this ruler to mark curves on leather and the ¼" hole anchor makes it really easy to pivot without slipping. The acrylic is clear enough that I can see my cutting lines underneath, which helps with precision.
