Thanks for the feedback. I was taught in a class to test all thread before using with a tug. And I did not have to pull very hard on it. It worked fine on my machine. These charity quilts can get some rough treatment so I will not use it for them and save it for something where I want precision. I bought it from Craftsy so am not trying to return it.
I quilt on an HQ16 and use Connecting Threads Essential Pro on that. It is fabulous. I don't have a bobbin winder and buy prewounds from Superior Threads. Bottom line I believe.
