The forming top die and the spring-loaded bottom die keep the shell centered; therefore, you get crisp edges and a modern, minimal look. Works with silk, satin, velvet, wool, cotton, linen, and blends. How it worksCut, load backer, place fabric and cap, flip, press on the MD-1—as a result, the wrap is tight and permanent.
