LORELAI: Oh, maybe we could add a little stenciling on the ceiling.
Stenciling is adding a picture or pattern to a design by using a stencil β a thin sheet of material with a pattern cut into it that can be painted over so the paint only goes into the patterned area. Stencil refers to the material itself, and the design it produces. One of the earliest of art techniques, found in prehistoric cave paintings, stenciling is commonly used in home decorating and DIY projects.
