Ok, I used to wrap tinsel on the shank of trout flies all the time, years ago. It was the flat type gold or silver, in several widths. It came on a spool too. If this is what you have, don't use a bobbin. simply cut about a 3" peice from the spool. affix it to the hook shank where ya want it, then wrap your thread forward to where you will end the tinsel wrap, let the thread bobbin hang there, while you spiral wrap the tinsel forward to your stopping point, wrap over it several times with the thread, and trim the excess. I think you would have been allright if you hadn't used the bobbin, because this stuff kinks very easily.
