- Waffle Flower Water Media Mat is a non-slip, waterproof and heat-resistant multi function craft mat. The smooth, matte, white surface is non-reflective. The suction back of the mat sticks to your table and will not move. If it loses suction, clean with water or a baby wipe to help it stick again. Use the palette squares to create and mix your own colors. The indented work area can hold paper sized up to 9 x12 inches. A glue gun or heat tool will not damage the surface and dried glue peels right off. Avoid sharp edges. Some colors or pigments may stain your mat but does not change the properties of the mat.
