Designing a stencil is difficult because of the requirement that all positive regions are connected. In this proposed method for generating expressive stencils, you simply use standard drawing operations, and the system automatically generates the appropriate stencil satisfying that constraint. You obtain the physical stencil by sending the result to a cutting plotter. Finally, you use the stencil to decorate the target object (for example, fabric or a postcard). In a workshop for novices, even children could design their own stencils using this system. The Web extra is a video that shows how the Holly system lets users easily design valid stencils from scratch.
