hello! i’m really sorry but i don’t know of any offhand! i know mayormeadow has a beautiful flower path tile as well as matching stones which you can find here, but that’s really the only thing i can think of!
otherwise, you might find something similar to what you have in mind by browsing through blogs such as acnlpaths, acpath, animalcrossingcloset (path tag), or merongcrossing (paths tag).
good luck, i hope you find what you’re looking for soon! and i hope you have a wonderful day!
