Tip #4 – Thread Identification
Very often we have a variety of our Norvise Bobbin Spools filled with different threads and we lose track of which is which. OK, so I have a few more choices than any reasonable person would ever need. I use the old “thread size” designation, 3/0, 6/0 and so on and I put a dot of red fingernail polish on the edge of the 6/0 spools.
Since I can tell the difference between the 3/0 and 8/0 by looking at them so I only need to identify the size in the middle. You can also use several dots to identify special threads, such as Kevlar, 14/0 etc.
