I've begun to wash the three fleeces (shetland and ? mix) given to me; confronting a sheep's fleece is a brand new experience...wow! Lots of bits to toss in the compost, tips to flick or trim, and quite smelly, in a barn sort of way.
I can't tell what the best parts are so I am just saving any of the good looking wool; I've washed three handfuls and it cleans up nice, except for those tips.
This first picture is of the grayer wool:

and this is the white with the dirty tips; I don't have a comb or flicker so before I wash more I may trim the tips.

I worked about three hours tonight in the shop and need to get up by five at least to get more work done; and even so I know I won't be able to finish. But I am just too old to do all-nighters anymore.
