How to do it
Cut different sorts of leather cords in the length you require to make a bracelet. Make silver-plated coils using a wire working tool and thread them onto the cords - attach a clasp.
Insert wire into the small hole in the base and screw the mandrel into the base. You can use mandrels in different sizes.
Insert your finger into the large hole in the base and turn clockwise while holding the mandrel and wire in the other hand.
When the wire is coiled, remove it from the base and cut it into the desired length or pull it longer.
Pull the coil over the leather cord/cords. Push the ends slightly using flatnose pliers.
