As you can see from the photo, the intricate design is brought about by carefully notching all four corners of a square tile–just enough space for a small square tile to fit. Yours truly spent several hours hunched over–and sprayed by–my wet saw. The trick to uniformity is to treat the problem like Henry Ford would: mass production. First I made all the left cuts; then switched my jig and made all the right-hand cuts. It’s frustrating, of course, when the tile breaks along a fault line on your very last cut.
