One day when I was sewing with 100% cotton Gutterman thread purchased from Hancock Fabrics, it kept shredding in my needle (Size 12 sharp). I got so aggravated and frustrated that I yanked that spool of thread off and replaced it with another spool that I had purchased at Joann Fabrics. There was an immense difference in the lint and also the fact that the Gutterman purchased at Joann Fabrics did not shred. I started checking on the internet through google and I found that there are two different grades of Gutterman threads. One is manufactured in Mexico and the other one is manufactured in Germany. All of my Gutterman that was made in Mexico has sense been discarded in the trash can and I no longer purchase Gutterma thread of any kind at Hancock Fabrics.
