These molds are a must have! Each kit comes with the short and tall molds of that size (enlarge photo) necklace end cones! They also come with instructions and a template for your clay.  Roll out the clay, use the template to cut the cone shape, wrap the clay around the cone, mend the seam, and let dry.  Once dry remove from the mold, sand and clean, embellish and then fire the cones.  Do not fire them on the molds.
