How often you create custom classes for small projects

Hi,

I have been using AS3 for over a year but only to create some web pages with simple animations using tween Engines like TweenLite etc. without having to rely too much on custom classes, one reason is obviously because I don’t know understand classes that well, even though I have created some re-usable classes like a class to add a glow or fade all my images or links when mouse over, but nothing fancy and I have been always curious as to how or what the pros do for small projects like a web site or a simple banner.

1- How often do you have to create custom classes for small projects, and for what parts of the project (navigation etc)?

2- Do you try to manipulate all of your MovieClips with classes?

The reason for my question is because I want to start thinking more about classes (OOP) and stop witting all my code in the .FLA file or a class using the Document Class (which is no different than putting it directly on the .FLA file) IF classes is the way to go.

Sorry if I’m asking something I should already know.

Thanks
