I no longer use Coats and Clark it leaves to much thread/crap in my machine...I only use Sulky thread. I buy when on sale...buy one get one free at Joannes...

Nice to know before i have these problems.

Hey ladies, after rethreading, changing the bobbin, adjusting the tension and freeing my machine of so much lint, I finally realized what the problem was. I looked at my bobbins, some had Singer on them and some didn't. I realized I was using the one that did not have Singer on it. During all the trouble shooting I changeed bobbin to one with Singer on it not realizing it could make a difference. The that is not a Singer bobbin fits very loosly in the bobbin case and I was hearing a little rattling of the bobbin but never thought it made a difference. I am going through my bobbins to remove the ones that does not have Singer on them. My machine is very cleaned and oiled now. Being sewing all morning. Thank you ladies.
