My modern Brother machine had been very trouble free for the 18 months I have had it. It was great and had 80 decorative stitches, was a strong stitcher, etc. I had no complaints about it at all.
About 3 weeks ago it started acting really strange, tangling bobbin thread, breaking top thread at the feeddogs, not moving the fabric through right. I set it on the floor and took out my vintage Singer 301 and Featherweight and finished a couple of projects.
Last night DH helped me get the needle plate off to take a look. Well, goodness!! No wonder it was acting strange!! I realized not once had I taken that plate off, and every single nook, cranny, spring, space, crack, feeddog track and all was packed solid with lint.
DUH!!! I just hadn't thought about it, since it's a drop in bobbin in front of the foot.
SO....CLEAN YOUR MACHINE!! I should post that over my thread rack on the wall. Sorry, little Brother machine....I promise not to neglect you again!!
