Well I took it apart and put it back together twice last night and finally decided on a piece of leather. Not creative at all, and what is worse I overlapped it a bit cause I couldn't get two beveled pieces to go together right. I think with a couple of Spanish rings it will look OK though. It's not part of the handle that will show much, and between a bit of two part glue and a couple of spanish rings it should hold forever. I have to let the glue dry 24 hours before I can mess with it though.
I see Brian, quit clever, so the bights are not interwoven the same way. I can't follow a grid to save my life though.
I wanted the top of the knob not to have a hole in it, but after thinking on it I thought it might look nice with some sort of cap on it too.
