Judy I'm getting "partial" shredding breaks......where it appears the inner core of the thread usually stays intact, but the outer "shell" gets all knotted up in the needle case area... ----- Original Message ----- From: OnleeJudy@xxxxxxx To: amayausers@xxxxxxxxxxxxx Sent: Thursday, December 15, 2005 10:31 AM Subject: [amayausers] Re: needles and thread breaks on nylon jacket Hi there. A couple of things to try...more backing, as nylon is very light, and sew slow....and depending on the type of thread breaks (clean breaks or shredding breaks), check needle alignment, and add or subtract MT. BEST WISHES!
