I remember liquid embroidery. I still have pillowcases my grandmother embroidered with the paints. The paint has not rubbed off or cracked in all these years and the pillowcases have been used a lot. She use to wash them in hot bleach water. The paint did not bleed or feather on the fabric. No special fixative needed that I remember. No one was allowed to touch her embroidery paints, they were very expensive to buy for a hobby and hard to find. I saw some at Hobby Lobby but I doubt it is the same quality as the original paints.
