This Stencil Mat from Waffle Flower Crafts is going to make crafting with stencils so much easier. This mat is made of high quality silicone and is a multi-function craft mat that is non-stick, heat resistant, and waterproof. What more do you need? This is amazing! The recessed work area measures 9.25" x 12.12". There are 2 raised edges that form a corner to help hold the stencil and paper in place and two open ends for bigger sizes. The back is non-slip, so your mat remains where you place it. When your stencil pastes and paints are dry, they are easily released from the mat. This mat is both heat and cold-resistant. This mat can be cleaned with a dampened, lint-free cloth or an oil-free cleaning cloth. Note: This mat should not be used with oil based products. Some pigments may stain the mat. Sharp tools will damage the mat.
