Best way to manage session in NHibernate?

Question

I'm new to NHibernate (my 1st big project with it).
I had been using a simple method of data access by creating the ISession object within a using block to do my grab my Object or list of Objects, and in that way the session was destroyed after exiting the code block.

This doesn't work in a situation where lazy-loading is required, however.
For example, if I have a Customer object that has a property which is a collection of Orders, then when the lazy-load is attempted, I get a Hibernate exception.
Anyone using a different method?

check out the SummerOfNHibernate webcasts for a great tutorial... What you're looking for specifically doesn't come until webisode 5 or 6.
