I've used only a small sample of it, didn't really think it was alot different using it for handwork. At guild the other evening a lady showed 2 quilts she'd just finished & said she found the bamboo had alot of "fluff" that floated around as she manouvered the quilt at the machine & she found it bothered her breathing. She said it didn't beard like some of the older craft poly batts but that the little pieces that floated were all stuck to the right sides of the quilt.
