On the right hand side chain continue with the exact same process of folding the 2 rings from the 3rd link back, one on each side. Part the rings from the 2nd link and take an open large ring and go through the 2 folded back rings. Before you close the large ring take another bead and fold back the rings from the 3rd link of the left hand side chain into the byzantine pattern, part the rings from the 2nd link and take the still open large ring through the 2 folded back rings. Close the ring. If you feel that you don't have enough hands when joining the 2 half byzantine patterns with the large ring, try using a piece of wire to hold the chain maille pattern in place while you attach the larger ring.
