I don't. I press binding in half before sewing it to the front of the quilt, then hand sew to the back. I like the way the binding turns out with this method so I'm not tempted to change it. There are people who don't press the binding in half before sewing, just fold it in half and feel that it makes a nicer binding that way. That method always sounds interesting to me, but so far I go back to my tried and true method.
