Professor Pincushion shares a video tutorial showing three ways to turn a hem around a corner. She shows how to make a simple corner, with first side of the corner folded down and ironed in place, and then the other. She also shows two ways of making a mitered corner. The mitered corner is a little more complicated than the simple turned corner, but it looks more finished and is less bulky. Go to Professor Pincushion to watch the video.
