Solved breaking thread problem
I've been sewing on a lot of quilt blocks lately & suddenly my tread has started to break & the stitches look sort of jagged on the back. At first I thought it was because my thread was getting close to the end of the spool & maybe there was a little burr on the spool that it was hanging up on so I changed out to a new spool of thread.....still breaking. Finally I decided to do a thorough inspection of the bobbin area & WOW did it ever need a cleaning! I cleaned it all out & now it's back to purring like a kitten. It's amazing what lint build up can do to your machine. I generally clean out the bobbin area on a regular basis but got lazy & haven't done it for awhile.....lessons learned!
