These Spiral Makers create perfect spirals out of Artistic Wire, German Style Wire and any other soft wire 20 ga (0.81 mm) and smaller. Use colorful spirals to embellish jewelry, scrapbooks and paper crafts. Use small pieces of the diameter wire you intend to make the spiral as a washer on the three screws. Tighten wing nuts and insert the same gauge wire into the device. Center the wire in the center hole and insert the twister handle so the wire is inside the slit on the handle. Twist the handle until the desired size of coil is reached. Tip: count the number of turns to re-create the same size coils for multiple coils, or perfectly matching earring dangles.
