I ...knocking on wood...lately have been having good luck with monofilament thread. In the past, I only had horrible experiences using all the techniques but the nets(use that for some of my serger threads). I've been using it on my quilted crafts/wallhangings in the bobbin and the top thread. I set my machine to slow and have it on the horizontal pin. Oh i am having luck with coats and Clark. Who would have thought? Not me!!!
