Soapstone is a naturally soft, delicate substance and should be handled carefully to reduce breakage. If it breaks, small pieces can still be used in the marking pencil. Soapstone develops a thin, hard surface when it has been exposed to air over a period of time. Re-sharpen the soapstone gently and scrape the point on a piece of sandpaper to sharpen before use.
To use: Mark fabric with thin lines. Do not iron over marks. Remove marks by gently rubbing fabric or washing fabric with plain water.
