Don't take the paths our because they don't protect you from grass wear!!1. I laid out paths to avoid grass wear. It was getting really bad, and you could tell it was happening. I didn't cover every square inch, I like being able to see the grass, and watch it regrow.
2. See above. I have a decent sized park, though, that's mostly covered. But it's one of my best features, it took a lot of time to make (I even sorted the flowers by color and type), and I'm proud of it.
