Thanks FM good choice of materials to use and they should do the job.Fatman said:Len
Just from looking at the picture it looks like it could be poly yarn or if you wanted to you could use a metallic sparkle braid.
If you really want to try stretching it out you could use wool and wrap it tight and even
If you don't want the flat plastic strip you can get some of the kids stretch cord which is round and you can use that. They have a bunch of different ones
The hook looks like a short shank live bait jig hook
