How to get fragrance to hold in hot processed soap?

How do I make hot processed soap and how can I get fragrance oil or essential oil to hold in the soap after it is made. What is the amount to use that will be enough and how do I make it happen?

There's a make-soap procedure here:
I'd add the fragrance when it's just cooled. See if there are any relevant comments there?
