I bought a bolt/roll of it several months back . I used it for the first time a month ago. I noticed the scrim is not as intregal to the cotton fibers as the warm and natural. When I preshrunk the batting in the same way I would warm and natural the scrim seemed to separate from the fibers. So for long term repeated washings , I am not sure it would hold up. I need to take a chunk .. create a mini test quilt the size of a potholder and toss it in the wash every time I do a load and see what happens. One of the reasons I like warm and natural is for those projects that I want to preshrink the batting Warm and Natural holds up the best.
