Calculating the length of coil required for x jump rings.
Example:
50 jump rings are needed from 1mm wire.
Make a coil 50 x 1 = 50mm plus 2 to 4mm extra
50 jump rings from 1.3mm wire.
Make a coil 50 x 1.3 = 65mm plus 3 to 6 mm extra
Using square wire
Do not allow the wire to twist when forming the coil. Hold the wire in parallel pliers and wind the coil slowly
and carefully so that the flat side of the wire is firmly against the mandrel.
