Dunno about that one Ferrara, but in my internet prowls, trying to find the words, I learned that tar is made from one part "roamy tar from America" and 4 or 5 parts rancid butter. Yech. I can see why you want to get it out.
I see everyone's words say "wove" twice. Thing is, when you are working with wool, first you shear the sheep, then you take the wad of wool and card it (pull all the fibers straight in one direction by brushing it between two big curved short toothed brushes). Then you peel it off one of the carders and roll it loosely (into a rolag) and then you feed one end of the rolag to your bobbin or spinning wheel and stretch it out while the wheel twists it up. Then you can think about weaving it, waulking it (slamming it around a table wet, to even it out and size it), and then cut it up and sew it.

Thanks Joe, that looks close to Helen's words. And the tune is just about the same.
