I used the bamboo batting on a baby quilt once. It was very easy to quilt through but since it was a shower gift for my sister's friend, I have no idea how it's holding up.
I only use Warm and Natural for all my projects because I prefer natural fibers.
Here are some other threads that talk about bamboo.
