The Crafter's Workshop Butter Spreader is made from sturdy plastic and designed to spread mixed media pastes, such as Stencil Butter, across a stencil. The tool's uniqueness is in the size. The Butter Spreader is 6 in. wide and allows perfect coverage for the Crafter's Workshop 6 in. x 6 in. stencils. The width will also give a more consistent application than using a palette knife.
