Minky used for backing seemed like such a headache when I tried to free motion on my regular sewing machine. But, with the Innova longarm, it was truely a breeze to work with. The trick was not stretching it when putting it on the frame. The sides tended to want to stretch out too easily. So I just left off the stretcher clamps and held up the edges by hand to keep it smooth against the batting and top. I think I could get away with using the clamps but not stretching them very much at all. This was my first so I wanted to baby it.
