Flooring Tile - 1" hex tile on bathroom floors...

I have a bathroom we're remodeling to look like it originally did in 1926 when the house was first built. It's roughly 8' x 7', and will have a clawfoot tub, and tile up to 48" above the floor all the way around. The problem is the complexity of the tiles we've chosen. Specifically subway tile on the walls with a black border where the tile stops (which shouldn't be too much of a problem) and 1" hex tile on the floor.

I've seen bathrooms where this hex tile is used to fill a field in the center of the floor, and a border (sometimes extremely elaborate) using 1" square tiles is used around the outside. The problem is this bathroom is not very square, so I'm having a hard time figuring out how to lay the border out. Typically I would think it would be smarter to start in the center of the room, and lay the tile out, but since we'll be using two different types of tile (the hex tile is laid out in sheets) I don't see starting in the center as being a good idea.

Any help and experience with this type of tile work would be appreciated. My only tile experience has been 4" and 12" mosaic tiles. This is my first time doing decorative tile like this.

Anyone??? - Bump

I've decided to dump the square tile border, and go with larger 1 1/4" hex porcelain tiles. More economical, easier to install and take care of, and all I have to do is set the molding, and from that I can run my wall and floor tile. Now I just have to figure out how many black tiles I want to have...

Thanks anyway.
