|Poppy's locks: unwashed on the left|
I've never had such blocky tips on covered wool. Good, bad or otherwise I don't know yet. What I do know is that the fleece washed clean very easily - and that surprised me, usually a very fine fleece is tough to de-grease. This one washed clean in two washes and two rinses. I could have kept rinsing but it was so white that I decided it was good enough. Here's a larger clump of clean fleece.
