I you are going to do both front and back on your machine, you do it opposite of what you do when you hand stitch the back..
First sew it to the back, lineed up with the edge of the quilt, using your walking foot and sewing a 1/4" seam..
Then bring it around to the front and top stitch it down with your machine.. again use your walking foot... You can match thread color to the binding on the top and if you want, use invisilble thread in the bobbin..
I know that there is another way to do this, too, but I dont care for the results as well...
