I should try new things but I do press my binding in half. I rarely use biased bindings. I just fold it over itself into about 12 inch lengths and tie a bit of selvage around it at both ends. this keeps it neat until ready to use as a lot of times I make the binding for the quilt before I quilt it unless I am planning on just using the trimmings from the backing. I don't pin my bindings on, I just start stitching them to the back using my walking foot then serpentine stitch to the front using my walking foot also, I have found that if I position the front just a bit beyond the stitching from the back and then position binding along the inner side of the toe of my walking foot, the stitch line is positioned just fine. Took a bit of practice to also get the mitered corners of the binding to lay nice but most of the time they are just fine now. I only hand stitch the binding on very, very, very special quilts. I have too much stash to stitch up!
