Yes, and in fact they form without wool thread at all, which is just as well, because sheep tend to be rather fatally poor at caving.
Once the wool is sheared from the sheep, it is cleaned, carded and spun into thread.
This needlework is embroidery stitched with wool thread instead of cotton or silk thread.
Thread is spun from fleece by spinners.

Cotton wool is made from the fibers that surround the seeds of the cotton plant . The difference between cotton wool and cotton thread or cotton fabric is that cotton wool is only cleaned and not spun into thread for use as something else.
Wool, Yarn or thread :)
The possessive form is 'the sheep's wool'.
Your answer depends on the thickness of the wool. A thread-weight length will be longer than a bulky-weight yarn.
The wool fibre is generally thinner and curlier than the cotton fibre, so for the same weight of material, a wool thread traps more air than a cotton thread. And for insulating purposes, you want to trap as much air as possible. With a denser thread, you have to use several or thicker layers to get the same result.
