Wow! I finally found someone who does binding ends as I do.

This is a long tutorial, but worth your time if you want to know how to join the ends of your binding. This works every time. The only thing I do differently than she did, is: I iron a triangle into the beginning of the binding, and when I get to the end, I don't need to trim anything off that end. I lay them down
carefully where they will be sewn and cut off the ending strip at the point of the
bottom of the ironed triangle. That point is exactly at the width of the binding strip. You can see that because the binding strip if folded down to there.
Then I finish the last seam as she did. No extra fabric to worry about.
Oh! one more thing. I open my seam
before I trim the extra fabric. It is so much easier because you have fabric to grab onto to get the seam open.
This is one of the reasons I love putting on a binding.
