My Janome HATES Coats and Clark thread so I was wary about buying the Connecting Threads thread, but not anymore. I have bought three large cones, Natural, White and Cornsilk and use one of them in ALL my piecing and bobbins. I save the coloured threads for topstitching FMQ, applique, etc.
There is a fair bit of lint from the thread when you sew and vacuuming or brushing out the bobbin case is really important but it is is 100% cotton and not polyester!
