Decorative Pathways

Good evening, after working around with unity for a little while now, i have become quite comfortable with the way it works but i am hung up on one thing, in my scene i am working on a house environment that would represent anybody's modern living space. what i cant figure out is how i would be able to incorporate a decorated path way into my game, when i say decorative pathway i mean some sort of tiled stone path in a specific pattern going to a garden or whatever you like, i thought about just texturing with real images but i soon found out that it looks EXTREMELY tacky, also i thought of just modeling each tile and importing it into my game but that seems like it would be too time consuming and there must be another way. I would assume that a 3rd party software would be needed so my question to you is how would i get an aesthetically pleasing outdoor modern day walkway into my game and what program would you recommend me using? Thanks a bunch guys, all of your answers are greatly appreciated!

too long? - i want pathways how can i do it :)
