Innovative Rulers that allow the user to use one side of the ruler on light colored fabrics and the other side of the ruler on dark colored fabrics. The rulers are hot stamped with a two-layer foil showing yellow on one side and black on the other. Rulers are made from polycarbonate plastic and are unbreakable! Designed for both right and left handed users. Read, measure and cut from both sides! These rulers are great for cutting strips!
