Does anyone on here have the Viking Emerald 118? I am trying to do free motion quilting with it and I can not get it to sew properly. Either the thread is to loose on the top or too loose on the bottom. When I first got it I took a class to learn how to use it and when I got home I practiced the free motion and it worked fine. Now I can not get it to work properly. I know there is probably some setting I am missing but I can not figure it out. I hope someone can help me.
