brother embroidery machine keeps shredding threads HELP
my Brother 1500D keeps shredding the threads, it has been in the Dr's twice and still shreds the thread, I am using Brother threads, and I have to rethread the machine every few minutes and sometimes seconds today I hadn't even cut the thread when it shredded again, this is so frustrating, any suggestions would be great. I have tried other threads and it does the same thing, I am threading the machine properly, so I am at a loss as to what to do next. sometimes the thread is twisted around the arm that goes up and down inside the machine and it is so hard to clean it all out.
