This is a great topic as I have had several warnings about serger thread in my sewing machine. One from my sewing advisor and one from the Huskvarna representative. They said it would be hard on my (very expensive) sewing/embroidery machine as it shreds more easily than the triple wound sewing thread. Also, they advised me to use only Maxi-Lock in my serger as in their opinion it was the better of serger threads. So, being a novice and not knowing too much, I have followed their advice. I use Connecting Threads cotton threads for piecing and general sewing; however I find they sure create a lot of fuzz. Anyone else have this problem?
