How to prepare wool to be used as stopping:
Get wool from a local farmer nearby you. Clean the wool from scrapping and part chunks. Rinse the wool from the sweat of the animal by soaking and very gently tugging it in water not warmer than 40 ‘C. This treatment leaves a great amount of wool grease in the wool. Dry. Finish by fluffing it up by parting all chunks of wool with your hands.
Wash wool if too smelly or dirty by gently soaking and very gently tugging it in soap water not warmer than 40 ‘C. Make sure the wool is only soaked for a short while.
