I have used BAMBOO batting frequently and have found it a very beautiful batting to quilt and sew with.
As with anything new, I did check out different forums and chats about it and came to my own conclusion that for me, it is the batting I prefer most.
I buy either the 100% bamboo or 50% cotton/50% bamboo battings and they have sewn and washed up beautifully with minimal shrinkage. My first quilt with this batting is now 4yrs old and is washed regularly and it is holding up very well indeed.
Below is a link to add to the information for anyone interested. Good luck to anyone brave enough to try something new.
