Ok, I tried to google this but didnt help... :p

I want to make my texture pack. Got Paint.net and
YES, I KNOW THE PAINTERLY -.-     But I want to create my own. No the painterly.
Got it? Dont dare to tell me about it again...

So if anyone could explain step by step how to get it from the minecraft.jar or give link where I can download non-edited texture pack of minecraft.

Reason why I want the non-edited texture pack is that I wanna create my texture pack idea I've had a while and there's some stuff I dont wanna edit and keep it original.
