fullajoy, your first viking knit is gorgeous! Love it in copper! I made my first the other day, in single stitch. I made two pieces and used wire-wrapped (gotta change that!) end caps too. I'll attach a pic. Can you tell me the finished diameter of yours?
As for cutting it, it shouldn't unravel, just grab the very end and wrap it tightly around another of the wires. It will be covered up by a cap.
I'd love to see more of anyone's VK, esp. double knit and any other more intricate types.
