How to Stencil a Ceiling Medallion

To keep paint from bleeding under the stencil, use an almost dry roller. Load the roller until it absorbs most of the paint, and remove excess by rolling it over a folded paper towel several times; it's better to have too little paint than too much. Move to the stencil, rolling with light to medium pressure. Peel back a stencil corner to check that you're satisfied with the coverage.
