What I do is pull the end yarn though the single remaining loop and pull it closed. Then weave the yarn in (just follow the path of a strand of yarn in the knitting), for a few stitches.

"There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open."
— Martha Graham
Thanks, Amy. It sounds like an obvious thing, I'm sure to those of you who really know what they're doing! I have knitted before but someone always did the end part for me. Thanks for answering right away. It was kind of you!
