The Ultimate clay gun extruder has many uses and is one of Yolanda's favorite design tools. With the 20 disc designs you can create many different embellishments for your cakes decorating projects. The round discs are used to help create vines, stems, borders, and letters. The screen discs used to create are for hair, grass, straw and floral stamens.The flat slot discs are for weaving basket patterns, lattice, ribbons and bows. The square, triangle, half round discs are for bricks, logs, borders, and can be cut and used for small beads. See how Yolanda likes to use hers in many videos including the Texas Cowboy Hat video!
