I think I actually use all of them in some spot on my island somewhere! My main paths are with the stone path, I think it looks nice and I like the sound it makes when you walk on them. I used borders at first but missed the sound when you walk over the path ):
for my plaza area's I use the arched tile path, I think it looks great next to the stone path ^-^
I also love working with 'stepping stones' it's the standard stone paths, but I just played around with the shape!
I did it by my entrance too with sand and dirt paths for the flowers ^-^
for personal gardens + my greenhouse I use the terracota path, I think it's really pretty and cosy looking!
I also have a little farm and used the light and dark dirt paths for that + custom flower designs
in my zen garden, zen spa and my campsite I used the sand path, dirt path and the wooden planks
I also use little custom flower patterns everywhere so everything blends together
I try to use different things on my island, so for my diner I used the brick path for the outside part and the wooden planks for the inside of the diner + the kitchen. I might change the wood for a custom design but I haven't seen one that I think would fit nicely with the diner
I can't find a picture of the front of the diner, but is has the brick path with some tables, chairs and a reception desk,
just like I did here with the bikes I placed a custom pattern around it with a flowery border ^-^
I do use custom paths all over my beach! I use a pink brick and a white wooden plank for that, and I really like it c:
I was thinking of making my town more pink (like my beaches) and used a custom code pink brick on my plaza, I tried it oud on a plaza that also has pink wedding furniture and I really like it! I still miss the walking sound though haha but because it's more for decoration then for walking I don't really mind (can't include picture because I hit the limit lol)
