pouring concrets for stepping stones

[Bgunderson]

Hi. I bought some molds to make my own stepping stones. I was wondering what kind of cement should I use, and can I just mix a little bit at a time, since I only have 3 molds and plan to make about 30 stones. Also, is it best to add color to the wet cement, or to paint the stone after it is set??? :?:

I'd purchase Quikrete's fiber reinforced concrete and mix it up in a five gallon bucket. It finishes with a pretty smooth finish.
