actually , eta, 55 lbs of wool, when washed, will yeild about 40 lbs of usable yarn, so--now think about it, even when skiing, or out in vermonts endless winter, do you wear 10 lb sweaters?

40lbs of wool= 640 oz of wool, and a heavy sweater is about 40 oz of wool.. so 16 sweaters, is a more likely number, or about 10 full suits!

the news is old news on knitting BB's!
(55 lbs of wool will yeild about 10 lbs of lanolin/40pounds of fiber, and 5lbs of un-usable stuff, (twigs/dag/etc)

merino is a particulary fine wool, the fibers about 1/10 the diamiter of a human hair, curly enough to be easy to spin, but not too curly, and long (though shrek's is partiularly long!) fibers, that yeild fine strong 'thread'.. its great stuff to knit with, and knitters who no nothing about sheep, know merino wool!
