Yellow fabric pencil for fine quilting lines that show on medium and dark fabrics. The firm core sharpens cleanly and resists smearing, keeping layout marks legible at the machine. Light marks may erase with the Unique fabric eraser; heavier marks generally wash out. As with all markers, test on a scrap of the same fabric. Built for reliable results in sewing rooms, classrooms and studios; always test on a scrap for best outcomes.
