Thread! Yikes, through the years I feel I have been told a lot of stories about thread. I even had an instructor tell us if we are sewing on cotton, we must use cotton thread, poly thread on poly fabric, etc. I think that's all baloney. I used Coats and Clarks for years and had no problems. I only shied away from it when I was "informed" that the thread was inferior. I would stay away from cheaply priced thread that is thrown into a bin at a store. None of my machines are fussy about what thread I use so I have a hard time getting behind purchasing expensive thread especially when the less expensive brands have stood the test of time. My girlfriend uses the large cones of Coats and Clarks for her free motion work and she swears by that brand. So once again, it's an issue that will continue to be visited again and again.
