Just finished these bangles. Originally they were to be connected to each other with a copper wrap. As it turned out, they were too big for me to do that (they have a very large core inside). To wrap around all three I would have needed to forge a copper wrap about 6 inches long. That was a bit much for my skill level and my equipment. So, I limited myself to a copper wrap on each bangle.
Individually, they work just fine (although the underwrap on one of them could have been a bit wider). These bangles are made with very interesting cotton yarns I got from Habu Textiles.
While I was cleaning up some of my kumihimo supplies, I came across another bangle that I hadn’t completed. Found some matching yarn for the wrap and finished that. This bangle is made with Gelli yarn (plastic) and wire.
