I have the same needle in that I was using before this started, I did check the bobbin case to see if there was any lint cleaned it out just in case no change. Also I'm using the same batting that I have been, started this quilt top a few weeks ago everything was going fine now this so extremely annoying! I have been doing other things and since the top is mine I was not in a rush to complete it. I will change the needle but I agree it's probably a tension issue because of where it is shredding, It's like when a knot gets caught up.
