Rather than go for the more traditional "dining room" approach, we've opted to create more of an outdoor living room, complete with coffee table and side tables. It gives the space a bit more of a casual feel, the kind of place you can just lounge in, and certainly eat if the occasion arises.
We started by building the frames for the tables. They consist of 4X4 legs, 2X4 supports, and a plywood base.
In order to put tile on, we added a cement board and began the tiling. We wanted to embellish the pattern a little, so we added some small tiles in between all of the larger tiles. While you can make the necessary cuts with a wet saw, in this case I used my nippers to chip off the corners of the tiles before I laid them down. The small tiles fit nicely in after that.
