Fabric marker - water erasableBOHIN water soluble felt tip pen is ideal for drawing marks that will no longer be visible after patchwork, quilting, sewing or embroidery. All you have to do is dab the pen marks with a clean, damp cloth to make them disappear. Please note: Test marking and erasing on a tissue sample beforehand. This pink ink also fades during exposure to the air within 1 to 7 days.
