Frixion Fineliner 4pk Black : Innovative, new marker pens let you write, draw, erase and revise repeatedly without damaging documents. Quick-drying ink won’t bleed through paper. Unique, thermo-sensitive ink formula disappears completely with erasing friction.
When using on fabric, write on the fabric, and erase the lines with the heat from your iron! Test on a swatch to ensure you do not end up with 'ghost lines'.
We do NOT recommend using Frixion pens for marking quilting lines as the lines can return when item is exposed to freezing temps.
Perfect for marking Half Square Triangle units, on the back of blocks, or in the seams.
