Skin Builder Tutorial

I attached a picture of the skin builder. I just imported the vista style. You can see in the red rectangle the area on the left to select, then what you can change on the right. you might need to add new entries on the right pane to cover all controls.  For example, if you need to change the font you can modify the skin using the skin builder and modify\override the system metrics for that skin, must set font for each type of control. 

I attached a second picture showing in more detail how to override the desired Font properties. I hope it helps.  This same method applies to all properties.
