I don't have laid paths or lined ones, but due to trees and PWPs and such, I guess I made some plain paths, empty, only grass, sometimes with clovers sprinkled around.
I had QRs paths in my old town and couldn't make them nice, so this is an alternative I'm enjoying a lot more!
I have paths lined with bushes. Might put down a pattern path sooner or later, but I think natural paths look nicer. If only I actually had time to work on them. ^^;
Sometimes I get a little nostalgic for when my town was pathless, but I'm too lazy to bother with it. Plus I've already built everything in my town around them, so...
I have stone and wooden paths that look good all year round., everywhere in my town. It's a Zen town so the wood looks really nice around it and where I want it to look more natural I use stones, clovers and mushrooms.
