I just bought 2 metres of Bamboo batting for a quilt I am working on now. I did prewash it and it did shrink like they said it would. I dried it in the dryer on the lowest setting and it took a long time to dry, but that took out most of the fluff so I am good to go. So far I have quilted 2 of the 4 panels of this quilt and I have a Janome Jem gold and it is handling it nicely. I don't hand quilt, so I can't help you there, but I did hand baste the panels and that went smoothly also.
I got it on sale for about $10.00 a metre and that is a lot better than the Warm and Natural that I pay $18.99 a metre for, so you be the judge. I only buy batting when it is on sale at 50% off, so I paid about 1 dollar more for the bamboo.
