Masked Harlequin Diamond Grid How to Make

Construct a classic, tailored accent wall pattern by taping out a structured grid of diamond shapes across a solid backdrop color. Coat your wall in a premium matte base color, providing a uniform foundation that serves as the grid background layer. Measure and mark equal intervals along the top, bottom, and side edges of the wall surface, connecting opposite points with light chalk lines to form repeating diamonds. Place painter’s tape along the chalk marks, leaving exposed diamond tracks that receive your secondary interior wall paint color. Roll two thin coats of your accent color over the open diamond sections, letting the paint set briefly before peeling away the tape grid to reveal clean, geometric diamond pattern work.
