Create endless cool patterns and designs with this Magic Ruler.
Secure the ruler with one hand on your paper. Insert the stencil disc into the larger geared circles, ensuring gear interlock. Position your pen or pencil in a small hole, then gently move it in a circular motion against the outer circle to reveal the pattern. Experiment with different pen colors and holes for overlapping designs.
