Oh lucky you....I have one also and just love love it...ok until last night...sewing along on my flanell rag quilt and clang/bang/grind....OMG what is wrong...I threaded, changed the bobbin nope nothing still didn't work...got my book out and started the trouble shooting...It ended up that there was sooooooooooo much lint built up under the bobbin case...whoooo hoooo...followed the directions to take out bobbin case, cleaned really good, put bobbin case back exactly like it says (line up red marks) and Whala it worked...the rag quilt is on it's 2nd wash then into dryer...Yep it pays to read the back of the manual book....
