Check out Miniio, a new player in the modern dollhouse world. Made of wood, stone, metal and non-toxic and food-safe materials, these structures and furniture pieces are 1:6 scale for Barbie and other fashion dolls. I have a feeling the structures might work well for 1:12 too...
Awesome news! Miniio will make 1:12 scale versions of their furniture items sans the pendant lamps upon request. These smaller items can be shipped to the U.S. and Australia. Contact the lovely folks at Miniio via email@example.com to order!
