This is beautiful bold Dahlia design is sure to brighten up any room! Use with a variety of shades of the same colour for maximum effect. The self adhesive stencils have a low-tack peel-off backing that eliminates the need for spray adhesive or masking tape. All parts of the stencil are held in place minimising bleeding and resulting in sharper lines. The backing is waterproof so can be cleaned, and once dry will become tacky one again.
