I have a question on free motion quilting. I do practice runs on the same kind of material and batting to get my tension set. And then I start the quilt. It is very hard to get a nice pretty stitch on the back of the quilt no matter how much time I spend getting the machine set. Then when you have to put in a new bobbin in the middle of the quilt, I almost need to remove the quilt and do some more test runs. I have a Bernina 170 and was not satisfied with the stitching on it. I brought a Elna 7200 with the wider area and in all honesty the stitch on the bottom is sure not what I thought it would be. Please help with suggestions. I have a pretty decent looking stitch on top.
