I may be wrong but I think the only method not mentioned so far is using the backing fabric as the binding. If the backing looks ok on the front I use this method as it does not involve having to cut or attach a binding strip.
This is the way I like to do it -

I don’t use glue - but that’s just a personal preference.
I once reversed this method. The quilt had a wide border - too wide for my liking - so rather than cut some off I used the excess it as the binding.
