Take the guesswork out of fabric selection with the Ruby Ruler, a unique tool that combines an acrylic cutting ruler with a color value lens. The red acrylic helps reveal the light and dark values within a fabric collection, making it easier to plan balanced, visually striking quilt designs. Measuring 5" x 5", the ruler features white markings in 1" grids with 1/8" and 1/4" increments for accurate measuring and cutting. A simple patchwork pattern is included to help you get started creating right away.
