Never thought of it as an "i" but yeah it is I guess. Specifically how the customer wanted it. I changed their stone selection and boulder steppers around. I gave my suggestions, bid against another contractor and was awarded the job.
The "waffle", again correct, but its called a pattern. Adds character or a design element, if you would, to the project. Anybody can throw down a regular 'ol flagstone walkway but thats boring. The walkway is random set 90 degrees with the home and the circle is not random. 18" squares only and set on a 45 with the home.
To each his own but once done it will have a clean classy look. You'll be more happy with the wall I started today. Lots of curves etc.
