What is the ideal amount of twist(tpi?) when spinning romney fleece "in the grease"? I am hoping to weave a soft "lap rug" when I am done spinning. I will probably make it 2 ply (just in case there are some really thin bits in the yarn.)
A: There seems to be two questions in #4 the ideal amount of twist? and spinning in the grease? Let me do the last one first.
Spinning in the grease is a personal choice that fewer spinners are making. In my mind it is a feel that you either like or dislike. I rarely spin in the grease now, but I like the feel (and smell) of a fresh clean fleece.
The amount of twist will not change, however you must be ready for the size of the finished yarn to change quite a bit since it will come clean and full in the first washing.
It would be wise to ply up a very small amount and make a little skein and wash it to see how much it changes in the washing. Save the little plied sample from question two, unwashed so that you can see the before and after difference.
There is no answer to the "ideal" amount for a romney. As I mentioned earlier size, plying, use, crimp and body all make a difference. However it is predictable that the yarn will be softer with less twist than with more since it is a lustrous medium type of fleece. So I would aim for the smallest amount of twist that plys back on itself and looks like good yarn.
Happy spinning, and remember to trust your instincts. Good yarn looks good, feels good and will be easy to work with whether knitting, crocheting or weaving or whatever. If you like the yarn you create and it works the way you want it to, then don't let anyone tell you it is not good yarn.
