I have recently used bamboo batting in two quilts and LOVE IT! It does not lint like cotton and you don't get the static like you do from cotton.
I used Maxi Lock thread in bobbin and needle on one quilt and Aurifil on the other and both gave good stitch definition. After washing I found the bamboo doesn't shrink as much as cotton.
Also, you can fold bamboo batting and leave it folded. When you lay out the quilt and fold marks come out in about an hour sometimes sooner.
I believe I'll be using bamboo in place of cotton for my batting.
