I visited a friend at Maleny and learned something new about wool. Marylou has a number of sheep on her property and she uses their fleece for spinning, knitting and felting. She told me that if a sheep experiences stress for a time then the fibres of the wool it is growing become thinner than normal.
This means that when the sheep is shorn then the wool fibres may actually break at the thinner part. The way to check for this potential problem is to pull on the fibres to check their strength.
