I guess I should start with the tools of my craft. These are some of the most primitive tools, Viking wool combs.They work best for long haired fleece and rough wool fleece. One of the combs is clamped onto an edge, a handful of fiber is thrown onto the tines and they are "combed out" with the other comb. After a few passes, all the fibers are aligned on one comb, while the "second cuts ( smaller pieces ) have fallen out and so has the dirt,chaff, sheep poop and insects. Left over is the sliver which can then be spun into very smooth, very fine , worsted yarn.
I did not use combs for the longest time when my children were still living at home. The pointy tines will draw blood. Also not recommended if you have anger issues.
