i had major problems with my singer (book is useless as are most owners manuels are nowadays) had trouble with all kinds of thread breaking bobbin making bird nests thought for sure it had to be machine then someone mentioned sometimes thread has to come off the spool a certain way well i didnt think this could possibly be it bobbin thread comes off back why would spool not also but noooooo it comes off the front they are so careful to mention in book about direction of bobbin thread but not spool why would they do this? my thought is so some nice repair man can make some money or get a good laugh at this dummy!
