Today I was working with 1 lb of this fleece. I found this one to be much cleaner than the 1st batch I did. There was a lot less VM too. It has an avg staple length of between 3-6". I ended up doing one stove top wash with 12 squirts of Scour. Next I did a stove top rinse with vinegar added. After that I did two plain hot tap water soaks in a bucket. I am really happy with the results so far. I will see what it looks like dry.
Skirted and in a bag for washing
