Whip finishes are knot the same as multiple half hitches, at least knot the ones I tie. Kinda like the difference between a double surgeons knot and three over hand knots. :hmmm Lets knot over simplify this for Carpy's and Beerfly's sakes, sheesh.
Here is a link to a whip finish article that claims to have a video. Maybe it will help you, Sammy.

Sammy, if you are going to use multiple half hitches, try to put each one behind the the previous one.
