I have never heard an instance of where this presented a problem for people who quilt on a DOMESTIC I have only heard this be a problem for LONGARM quilters. Most likely the reason being the disparity in the size of the needle. By comparison, a longarm needle looks like a harpoon when placed next to a domestic sewing machine needle. All of you who have posted that you have never had a problem, what do you quilt on?? If it is a domestic, then there you go. If it is a true longarm (not a stretched domestic like a baily) that uses the big needles, then you have been lucky. It only needs to happen to you once and you will pay attention.
It has happened to me.
The warm company does not put a warning message in their packaging for the most likely reason that this issue only effects a very small percentage of their customers, the longarm quilting community. And most longarmers are aware of the issue and don't like using W&N batting anyways. I know W&N is at the bottom of my list of go to battings.
