>>6180668For 1/12 western sites there's
Miniatures.com. Its a general retailer so there's a lot of brands and a very very wide range of prices. I'm not sure of others but there's a few dollhouse miniatures magazines that most Barnes and Noble will carry, and there's always a shitload of artist sites and other retailers in there.
As a quick note, in the dollhouse hobby theres slightly different scale terminology. 1/12 is called one inch scale (cus one inch = one foot). 1/24 is half inch, 1/48 quarter inch, 1/144 is dollhouse's dollhouse, and occasionally you'll see 'playscale', which depending on the site can mean 1/6 or 1/16 (cus older toy companies tended to make 1/16 dollhouses for some reason).
