Miracle Marker makes GREAT lines Sharpens by drawing across sandpaper or shave with a knife Each bag contains 3 markers To remove: *Using your iron on its cotton setting, iron off the markings. Heat is the removing force. Helpful Hints: *When testing the removal of the marks, be sure to place a scrap of batting under the test when removing with your iron. *When testing, if the iron is not hot enough, or you do not have batting under the fabric, the mark may leave a shadow line. If the iron is hot and batting in place and the shadows remain, do not use the Miracle markers on this fabric. The fabric is either not 100% cotton or the chemicals in the finishing process of the fabric are binding with the product creating the shadows. *Do not use product with cotton sateen. *Remember to test any and all marking products to avoid disappointments.
