I use a wool batting from LQS, not sure of the brand. It machine washes and dries beautifully and makes the quilt soft and fluffy, also warm in winter and cool in summer. The last quilt I outsourced for quilting, the longarmer used a very thin wool batting, as well as dense quilting; it turned out stiff like a tarp. I tried to soften it by washing and air drying in my dryer, but the batting dissolved, leaving the quilt a wrinkled mess. I was so disappointed. Now I do my own quilting on my Juki 2010Q. It's not perfect, but I am learning so much and having fun.
