Once the project has been squared and the binding is pressed in half (bias or straight grain), I stitch to the back after auditioning coverage from the front. I think the next steps are very important. Press the binding outward (away from the project), and sticking the point of your iron into your mitered corners to assist in formation on the frontside. Turn over and then press the outside edge again. This slight compression of the thickness is helpful. Since the binding strip is pressed in half, there is no guesswork in keeping the width consistent. Take time now to prepare the mitered corners, pinning and repinning as necessary. It is easier now than when the project is under the needle. Lastly, I use a decorative stitch on the front. (Owing to right-hand surgery, I am having difficulty hand stitching, although it is improving.) — I believe taking the time with the iron Is so important.
