I am not the best at my hand skills and it takes me forever, but I hand sew the binding on the back. I put it on the front by machine. I use pins, no glue. Mitered corners, "invisible" final seam.
I almost always make French fold continuous loop bias binding. I typically cut a bit wider than most people, at 3". For the last few months I've been trying not folding and pressing my binding first as recommended in a thread here. I don't really see any difference in the fold or not, but as I said, my binding tends to be a little wider and I often use a puffier batt than many people.
I tried putting on the binding with the machine both sides and just didn't like the finish and/or just never learned to do it well.
