Knee Lifter

June E Hudspeth

Good Evening Everyone:  Looking for some help.  I tried using the knee lifter today, to do a "variable zigzag" project from the FB Janome 15000 Workgroup group.  But, no success, the upper thread kept breaking, I tried adjusting the tension, changed the yellow dot bobbin back to normal bobbin and still not luck.  Only bit of luck I had was using regular thread instead of embroidery thread.  Any thoughts/suggestions??????????  I had never used the knee lifter before.  Thanks!!!!!!!!!!!!!!
