If you're remodeling a vintage home, you need to know about New Metro Tile. I searched a billion places and finally found this one. When I did find one inch hex elsewhere, it was $10-$13 per square foot. Then they had to order it, usually a week's wait. Here the tile was something like $5.50, and they had it in stock. You can get hard to find subway tile here too. Nice people. A little hard to find, but worth the hunt.
