I was surprised to see that 1:12 furniture actually works okay in the Villa Sibi dollhouse. Above are some quick tests to play with the space. The pool that comes with the house does not work so well with 1:12--it's better scaled for 1:18 or 1:16.
Maybe I'll get an opportunity this weekend to set up a real 1:12 scene. No promises though because I broke my New Year's resolution and brought a ton of work projects home. Argh.
