I'm in the the dumbass club! a few months ago my brand new janome suddenly started making thread nests in the bobbin and making a horrible noise, it wouldn't even pick up the bobbin to bring it to the top, the last thing i had done was use the htread cutter, i love that thing!i took the bobbin area apart as far as i dared to see if i could see what went wrong, for 3 days i cussed and cried waiting for monday so i could take it back to the dealer. patrice said "did you rethread it?" i was very adament that the problem was the thread cutter! i wouldn't even try rethreading. finally on monday afternoon i called to be sure the guy was in, 75 miles away, he said "did you rethread it?" i rolled my eyes and said IT'S THE THREAD CUTTER! he said well let's just try it. so i did, guess what :oops: the thread had come out of the takeup lever. you know patrice enjoyed it!!
