[QUOTE=AprilM;8720598]You arent the only one to wonder about this - been there, done that!
I asked around to get some advice on this one and a friend told me that when she binds by machine that she sews the binding on the backside and flips it to the front so that you are machine finishing the binding on the front side. You dont need to change the width of your binding. You are making the front look nice and neat because you can actually see what you are doing. You will see those stitches on the back so just load the bobbin with thread that matches the back.
This the method I use too, that way I see only one stitch line on the front, and as mentioned, I match my bobbin thread to the color of the backing. I most common on my donation quilts just make my backing at least 2" wider all the way around, I then do my quilting, trim the batting even with quilt front with scissors, and then trim my backing to 1.5". I fold to quilt edge, 3/4" wide at that point, iron, and fold to front and iron, clip and stitch down. I use my stitch in a ditch foot to ride along the edge,, offset my needle a bit to stitch it down. I like this method too because I get a perfect miter corner, I set my binding top and bottom, then both sides, my corners are perfect. Either method works good for me.
