Where should the border of the diamonds be located when checkering?

When checkering, the border of the diamonds should be located on the outside. This placement creates a clear and defined outline around the checkered pattern, enhancing both its visual appeal and functionality. The outer border helps to maintain the integrity of the checkering design, ensuring that the diamonds are prominently featured. It serves as a frame that draws attention to the intricate detailing of the checkering and provides a finished look to the workpiece.

Positioning the border on the outside also contributes to the grip's effectiveness, as it helps to encapsulate the checkered texture, enhancing the user's ability to hold and manipulate the object securely. Additionally, this approach prevents wear and tear on the pattern itself, ensuring that the checkering remains distinct even after extended use.

While the other options might suggest alternative placements, placing the border on the outside is the standard practice that supports both aesthetics and functionality in woodworking projects involving checkering.
