OMNIGRIP ruler is a precision measuring tool for quilting, sewing, and fabric crafts where accurate cutting matters. This ruler size is 5-1/2" x 5-1/2" (14 x 14 cm), which works well for measuring, trimming blocks, and cutting repeated pieces for patchwork. Use on a cutting mat with steady pressure, and store it flat so edges and markings stay dependable over time for consistent results across your project.
