flytire 0 Report post Posted March 16, 2008 its a retainer for loose end of thread. just slip the loose end of the thread between the spool and the cap. ok to leave on when in the bobbin this is tinsel but its the same with thread check out this thread chart for sizes http://flyfisherman.com/ftb/ssthread/index2.html Quote Share this post Link to post Share on other sites
utyer 0 Report post Posted March 16, 2008 Your thread is measured in denier weight. The larger the number the more 9000 yards weighs. So a heavier thread will be thicker. The ought sizing system is not uniform from one manufacturer to another, and not always the same in the same manufacturer. 70 denier is a finer thread closer to 6 or 8/0 while the 240 will be loser to a or 3/0.
