Welcome to the Stencil Supplies group of SmartGuy.com. Feel free to interact with other professionals from across the world.

Stencils produce an image or pattern by applying pigment to a surface over an intermediate object with designed gaps in it. This creates the pattern or image by only allowing the pigment to reach some parts of the surface.
