Stencil

A stencil is a template used to draw or paint identical letters, numbers, symbols, shapes, or patterns every time it is used. Stencil technique in visual art is also referred to as pochoir. Stencils are formed by removing sections from template material in the form of text or an image. This creates what is essentially a physical negative. The template can then be used to create impressions of the stenciled image, by applying pigment on the surface of the template and through the removed sections, leaving a reproduction of the stencil on the underlying surface. Aerosol or painting stencils must remain contiguous after the image is removed, in order for the template to remain functional. Sections of the remaining template which are isolated inside removed parts of the image are called islands. All islands must be connected to other parts of the template with bridges, or additional sections of narrow template material which are not removed.
