I'll try this again - it doesn't seem to be a popular answer.
But it's mine and I'm sticking to it.
And there's no Wickipedia link for it...I apologize.
Footballs have laces (the white line of stitching on one side) and two white stripes towards the ends.
Hold the football with your thumb and index finger parallel to the white line (not the stitching) at the end.
Your ring finger (and maybe even your middle finger) should touch the stitching.
As you hold the ball...your thumb and index finger should form the letter C - and there should be space between them and the ball...only fingertips make contact with the ball.
The ball will seem big for a small hand.
You may have to hold close to the end.
You step into a throw with your opposite foot - toe pointing to your target.
The ball starts up behind your ear - as you propel the ball forward
(stepping with opposing foot aimed at target)
...you lead with your elbow ... ball held above your head...
when you release the ball, your wrist flips downward to encourage the ball to spin...
Practice that a few times and you'll get the hang of it.
