I have a roll of Warm and Natural. I have used Hobbs wool (quilted like BUTTAH! but not machine dryable), Hobbs 80/20, the green batting made from pop bottles (I think that is quilters dream brand),Hobbs poly down (loved this and am saving up for a roll. Thinking I will use this for kids quilts and such.) and the bamboo one from Joanns (that was for a customer and have not heard if she liked how it washed. Heard it was from a renewable source, but hard on the envionment to make. Have not done my homework on that. Just hearsay.) Gee...I thought I only used Warm and natural! lolol
