a question: the thread at the craft stores is hand quilting, machine quilting and regular sewing but I have not noticed at Connectng threads there is not that distinction. What do you all use and why. My machine has started jamming with fizzes when I do free style and I'm wondering if it is the thread. I took the machine in and that was a week ago and now it's doing the same thing. I have always hand quilted and this is my first real project doing free style. Any suggestions?
