New Theme Help how to begin.

I want to begin to work on a new theme based on Precision original
Where do I find it to load in theme builder?
Icons etc.....
I really cannot think that people that makes a theme have to redo all from scratch!
Thank you very much

I hope to do something with HT TR and more based on precision.
I post here when I am done

search ur installation directory.. the stock icons are there..

its in there.. I dont have a pc so I can really tell u the path to follow off the top of y head.. but its all in the folder where the theme studio installed to..
