A Wire Jig is a kind of board with pins where you can wind the wire. It is used for making jewelry.
And now I know how to make my own wire jig.
As you can see on the photo I gathered the pins already, I only have to find a wooden plate ;-)
And when you gathered all the elements of the wire jig, you can begin to make beautiful wire jewelry.
