I usually don't bother with interiors. Hornsby's was kind of ugly, with literal thrash on the floor, but then I gave him plenty of cool stuff and now it isn't as bad (although he does seem to refuse to replace the original stuff, only adding more furniture instead.)
Slightly (un)related, does anyone know what happens to villagers with starter homes after they are adopted? Do they keep their four wooden furniture items and bare rooms?
