My wife is trying to sew two elasticated girdles together. as the material is elastic and to retain the stretch, what is the best type of thread to use. We have tried 'sewing elastic' type thread but that jams in the eye of the needle and breaks. Is it possible to sew elastic garments such as this and if it is can you also advise on the thread tension setting. The machine is a Husqvana classic 105. many thanks Peter
