"To find out a fleece I paid for weighs less when it is clean . Truthfully that did surprise me."
after washing 10 fleeces so far I have discovered it is only that one that was such a big change in the before and after weight. Not one of those other fleeces changed so much. The other fleeces I got including the free real bad ones still washed out to weigh very close to purchase weights. The best ones so far were the oatmeal romney and the chocolate corriedale. These two dealers had the cleanest and easiest to prepare fleeces. I actually bought more than one from the oatmeal romney farm. The hardest to clean was the white shetland. The black and white shetland came prewashed and was superb. The white shetland had hard to soak tips. Not unexpected but just a different cleaning than a more open fleece tip. I also noticed BIG differences in the carding of the fleeces washed like this. When I washed them in mesh bags and more packed together I had all kinds of little 'noils?' in the cards and sticks and dirt. The big tub method made a very big difference in how much 'stuff' falls or floats out of the fleece. I still have some assorted bits and pieces to clean up then I am done.
I do know now that a change in before and after weight is expected. I don't think anyone was trying to fool me. Experienced fleece buyers already knew it. As a newbie I just thought it was gonna turn out to be more. But still if I had known the projected before and after weights of fleeces it surely would have been included in the math of cost of fleece for me.
