Our LIP Templates are designed to match each form to give you about 1/4 inch perfect lip around our fun shaped forms. These lip templates also help in cutting clay down to size for the dual drapes both single and deep (if you place the template down first then put the form/drape on top and place your clay on top of that) this is how they were designed. Lip templates have a small edge that touches the clay so they are reversable and it will not matter which side (black or wood) touches the clay. For the larger rim area of RIM templates use the wood side for faster release, thought the black side can be used it just takes longer to release.
