I am really interested in this post as I have just bought a Pfaff select 2 and it sews beautifully but I have just FMQ my first quilt...and bought King Tut on the advice of my quilt shop as being egytian cotton and excellent quality but it has broken far more than any other thread, both in the needle and bobbin...tension was fine and new needle inserted (Organ 14)...so was it the thread, machine,needle or me ?
