Ending Mattress & Kitchener

I know how to begin mattress stitch and kitchener stitch, but I’m afraid I don’t know how to end them. How do you make sure it’s all secure? I’m paranoid about it all coming undone.

If you securely weave in the ends, at least through 5 or 6 stitches on the back side of the work (at least that’s what I do), it will not come undone. Honestly. There have been times that I’ve had to un-do a seam to redo it for whatever reason and I have had a hard time undoing it even when I wanted to! It won’t come undone all of a sudden on its own as long as things are secure.
