Dear Wise ones.
I am very happy with my new Viking Serger 905. As I am not a professional, and sew mostly clothing and things for our home, I am reluctant to invest in huge quantities of cone threads. In Clotilde, they show two gadgets. One uses wound bobbins to supply thread, and the other claims to make it possible to wind almost any threads onto spools and then use those, making it possible to use only one cone. Has anyone any experience with either one, or with other better items? Advice would be welcome. (I do not sew baby or childrens clothes.)
