This OMNIGRID acrylic ruler supports precise measuring and trimming for quilting, sewing, and craft projects. Sized 4" × 4" (10.2 × 10.2 cm), it combines edge markings with the OMNIGRID double-sight line system so reference lines stay visible on light or dark fabrics. The compact grid format is easy to maneuver for miniatures and detail work when squaring corners, trimming units, or checking small measurements.
