Help

I have a moss question. If I want moss to grow between bricks on my driveway (5mm gaps), can I just cut moss up, put it in, and water it? Will it grow (there's residual soil between the bricks as weeds grow there)? There's loads of moss (sphagnum amongst others, nearby) which I could harvest. Or do I need some kind of mix with a culture (like moss and milk, or something)? Is there any particular type of moss? Any advice is appreciated.
