If you want a fabric marker for 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 hours/days and will not reappear. Lines can also be erased by simply dabbing off with water. This pen has a fine, ceramic rollerball point.
