I love the byzantine pattern. And, it is relatively easy to put together, once I remember the order. For this, I wanted something long and versatile. I used 16 gauge, 5/16" aluminium rings.
The necklace is about 68" long. I have worn it long, doubled, or with a knot in it. There is no clasp.
The bracelet is double-wrap length, so could also be worn as a choker.
Here it is with a knot in it. However, I realized as I started posting, that it isn't the best picture of the knot I usually tie. It is basically an overhand knot, with only one strand on the over; it has a slip knot effect on the bottom loop.
Here is a close-up of the byzantine pattern.
