I have used the bamboo batting. Love the way it quilts BUT hate the expense!!!! Even for craft sized package (baby quilt maybe) it's as expensive as a queen size roll of cotton batting. DD #2 loves to use the scraps for her little projects - mostly bookmarks. Haven't washed anything as it's all been used in tablerunners or wall hangings. Will need to find a good sale before I buy any more of it and am not sure I will buy more of it. Recently found a partial roll of batting that I was unaware of its existence in my house. Definitely need to do more digging in the disaster area known as my craft room. :)
