Serpent's Spine is a unique weave similar to a series of coif beginnings stacked upon one another. It makes a thick, round chain with a spiraled appearance which is particularly striking when two metals are used. Two ring sizes are needed for this weave; one large and one small. One pair of sizes that works well is 7/16" 16 gauge large rings and 1/4" 18 gauge small rings.

For these instructions, green and blue rings are horizontal large and small rings, respectively. Red rings are vertical rings. The small rings should fit inside of the large rings:

Step 1: Pass a vertical ring through a large ring and a small ring.

Step 2: Continue adding vertical rings around the circle. You want a fairly large number of rings, but don't pack them in too tightly.

Step 3: Add another large and small ring through all of the vertical rings.

Step 4: Add more vertical rings, going through the two new horizontal rings, but not through the first two horizontal rings. To create the spiralling effect, make certain that all of the new vertical rings are to the left (or all to the right) of the previous vertical rings.

That should do it. Repeate steps 3 and 4 to lengthen the weave. Good luck!
