I took over my boyfriend's town long before I was finished with mine, so I know what it's like to manage two towns :3 It's difficult, but fun at the same time! I'd say build all the pwps you want first, then move your dreamies in, then landscape around your pwps and villagers' houses, that way everything is in the right place and you don't have to worry about a villager moving in and killing your flowers. I'll be sure to visit your dream address when you have it up ^~^

I let my villagers move in random places and worked around them ^~^ I like the idea of having a more natural town vs a more organized plot resetting town. I was really happy that Marshal and Mitzi ended up being neighbors! Their houses look so good together. I run where there's space to to help create my dirt paths, but I can only run a short distance before I run the risk of killing flowers lol I don't think I've ever seen road based patterns (unless you're talking about things like brick path patterns?), I just use custom designs to cover my town square and the area outside my train station. Like I said, I'm super addicted to landscaping

It's another one of my favorite things in this game.
