Since I bought a "Knit Picker" while at JoAnn Fabrics, I have not had any problems with the Shorb Loop.

"Knit Picker" cost less than $2.00. ~Parnelli

For my furled leaders I use "Mercersed Cotton Thread", it is very strong and sturdy. Is available in verious diameters. I usually purchase white thread and then dip the finished furled leader in a cup of colored dye. Since most of my fishing waters are either slightly green with algue particles, or reddish brown for marsh material staining the water, those are my two colors that I normally use.
