You know what really frustrates me - none of the battings that I have mention anything at all about a right or wrong side on the packaging. Even when you go to the websites, they don't address bearding.
Recently I found out that you are supposed to put the "dirty" side of W&N up and thankfully I have just been lucky and have done it this way probably 99% of the time. After hearing that I lloked at the packaging/strip of paper that comes with it on the roll and don't see any mention of this. Am I missing something - sometimes I can look and look and still overlook it. If I am not maybe we all need to start emailing the manufacturers that this needs to be on the packaging!
If you buy batting - you aren't going to go to their websited each time you use something else to see if there are any special instructions.
