Step 2Make large and small jump rings
iImage Information

You will need two sets of rings for this project, a set of N 12 ga rings with an internal diameter of about 0.5" and N+1 14 ga rings with an internal diameter of about 0.25" or so--something large enough to accommodate two 12 ga wires--the little rings hold the big rings. In my case, N was 19 (19 large rings, 20 small rings) for a necklace that is ended up 19.5" long. In the pictures, you can see the forming of the larger jump rings by winding the wire on a mandrel. In this case, I'm using a jump ringer and a 0.469" mandrel. Once you have a coil, you then use the jeweler's saw to cut down one side of the stack, separating the rings. Do this again for the small rings.
