Use this Creative Grids ruler to mark out twelve 30 degree triangles. Sew these together and you have a complete circle; cut out six to create a half-circle; or three to create a quarter-circle.
Or, use the angles to create a variety of intricate 12in finished blocks - no paper templates required!
Made from acrylic, this ruler has a non-slip backing.
