Congratulations on being a new quilter. It sounds like you have some of your quilting terms mixed up. I am assuming that you already have the quilt made and quilted except for the binding. If it is already sewn down on the face side of the quilt all you have to do is fold it to the back and whip stitch it down so that as little of your stitches show as possible. You should fold it tight enough that the stitches that secured it to the front are hidden. I have done it so many times that I just fold it over as I go but it might help you to secure it ahead of time with either pins or clips. Then remove them as you complete the sewing.
