If you want a fabric marker for instant projects, that gives clear lines that are not furry, do not bleed and can be easily erased this Sewline pen is for you. The Sewline ink is a special formula that does not bleed and keeps a sharp edged, fine line. The drafting lines will then just vanish into the air over a few days and will not reappear. Lines can also be erased by simply dabbing off with water. This pen has a fine, ceramic rollerball point.
