Brush Tool Tutorial

Well, my friend asked me about brush tools the other day,
as in my college work I had little butterflies and roses and she didn’t know how to do it.
So I thought I would give you this so I can hopefully help other people too.
*All of these brushes in the tutorial/examples can be resized in anyway, to your preference.
*I am using Photoshop CS2, so things may vary in different versions of the program.
*All examples are below their explainations.
*More detailed look into the brushes are in the images, so please click the pictures to enlarge.
