ive used the bamboo batt from the dream company- it was very nice to work with- and 4 years later the quilt is holding up wonderfully- through a washer/dryer many times-
i had picked it up just to try it- used it on a (picnic/beach) quilt-lots of wear & tear...i had no (pilling) problems---a problem with it migrating out of the needle holes could just be from the thread being used being a heavier weight thread- (just a guess- i didn't have the problem- i use 60 wt thread normally for hand quilting/needle to match-
all (manufactured batts) go through quite the process- just the nature of manufacturing-
