For two years, my sewing machine was a nightmare. The thread kept breaking or the sewing machine said the thread was broken, even when it wasn't. I couldn't sew but for a couple of minutes at a time before this happened. It was horrible. I hated my new machine. Then I bought a cone of Gutermann thread and I haven't had a problem since. No more thread breakage. I just bought some Prescencia thread and it works fine also. So, my machine loves the cones. I bought a really nice cone holder that has a cover with a hole on the top and a metal stick standing on top with a loop to put the thread through before you thread your machine. So, why would a machine like a cone over regular thread? Any ideas?
