Woolen drafting is the way I learned to spin. It's the draft that made spinning finally click for me. I could talk about it for a long time, but I will stick to three things.
It makes any preparation loftier. My favorite spin is a woolen draft on a worsted prep. I am willing to sacrifice shine and some consistency for the air in there. I like how it looks and I like how it knits.
I particularly like a backward woolen draft. You can see me draft in both directions in the video below.
It makes woolen preparations a bit happier, and more consistent. Woolen preps are pretty uneven, there are different lengths of fibers in there and they are squiggling in many directions instead of lined up.
When I spin a carded roving or a batt with a woolen draft, I can control the consistency better by letting the twist enter the fiber by itself. It seems to catch the fibers in the disorganized prep better that a worsted, controlled draft. At least for me. I also think, this is so much my opinion, if I go to the trouble of making an airy preparation, I want to showcase it, not squeeze the air out with a worsted draft.
It is, for me, a faster draft. If I want to knock out a braid, I will spin it with a backward woolen draft. It is my speediest draft. In the video below you can see my method. That is 100% my everyday, default draft. Just watching it makes me relax. Yes, the birds are always that loud in my yard!
Give a backward woolen draft a try and let me know how it goes for you and if you like the yarn!
