I created a couple custom templates for use in my lapidary hobby, to help create cabochons from stone. Each template has ruler markings on one end, with increments of ¼". The templates are 4"x6" overall, with varying shapes/sizes as shown. If you're not seeing a shape that you would like to use, just message me & I'd be happy to put together additional templates!
The author marked this model as their own original creation.
