The pattern is based on a Texas Farm Road sign. The standard Texas highway sign (photo at right) is a bit plain so I thought these farm road signs would make a much more interesting cross stitch pattern.
The Farm-to-Market and Ranch-to-Market road system was established in 1949 as a project to provide access to rural areas. You can read more about these roads on Wikipedia.
I can easily customize this pattern for any of your favorite Texas roads! Texas Monthly has this great article on scenic Texas drives.
