This OMNIGRID acrylic ruler supports precise measuring and trimming for quilting, sewing, and craft projects. Sized 1" × 6" (2.5 × 15.2 cm), it combines edge markings with the OMNIGRID double-sight line system so reference lines stay visible on light or dark fabrics. Use it to keep repeated cuts consistent as you square blocks, trim pieces, and verify allowances during piecing and assembly, This supports cleaner joins and more predictable piecing.
