Hi Joan,
When i did my first ever binding, I used Youtube videos a lot. I watched them tim and time again, found the ones I liked the most (one for mitred corners, one for finishing the binding) and then had my laptop next to me with the video runnin, so I could follow what they were doing as I was doing it myself, pausing whenevr I needed to.
This is the video I used for joing the binding ends:

Good luck!
