This wool is exceptionally soft and luxurious, and the colors are bright and beautiful. It does shrink and felt with even gentle washing as expected, but that is its only drawback. If you're looking for soft, warm, and beautiful wool, this should be your first choice!
I've used this yarn for years, and the wonderful feel and excellent quality can be relied upon. I don't believe I've ever encountered a knot which, in tonals and prints, can have a real impact on usable yardage, and it is one of the strongest single-plies I've used. The color may vary greatly from batch to batch, so it may be worthwhile calling JBW before placing an order to find out exactly what they have on hand.
