Yup. Tis true. Leftover soap in your yarn, fiber or finished wool pieces can break down the fibers. But there is an easy, inexpensive way to counteract this. Vinegar! Of course, it’s the next best thing to duct tape, right?
After washing your fiber, soak it in a bowl of water with a splash of vinegar to neutralize the soap. Lemon juice works great too and smells a bit better.
Happy fibering!
