Use the Dritz Mark-B-Gone Marking Pen Combo Pack to draw applique lines, trace weaving sketches or mark quilting and needlecraft designs. This pack contains two water-soluble marking pens in blue and white. These pens are ideal for transferring pattern markings and for marking exact locations of buttons and embellishments in your fabric-based projects. The blue marking pen is used for marking light fabrics and the white one for dark fabrics. Wipe off the markings made by these pens using a damp cloth. For best results, use only on washable fabrics.
