Lower thread tangles and machine then locks up
I recently took my machine in for repair for this problem and when I got it back, it worked fine. As soon as I had to change the thread (both upper and bobbin) the same problem started all over again.
I start sewing and then it makes a "clunking" type sound and when I take the fabric out from under the presser foot, its all tangled up.
I have read the manual over and over again, pulled the shuttle out and made sure that area is clean. I don't know what else to do. Please help.
