Hera Fabric Marker - What is it? The Hera fabric marker is used for marking fine sharp lines directly onto smooth fabric like you use for quilting. This fabric marker tool can also be used with carbon paper. The Hera Fabric Marker is unique because no powder is used. The curved end makes the mark and moves smoothly without damaging the fabric. Pressed firmly on smooth fabric, the fabric marker makes a fine imprint without damaging or marking the fabric.  The slight crease is a sewing guideline that can be pressed away afterward. When you use the Hera Fabric Marker, the mark can be used to fold the fabric . Thus a curve can be marked, folded back and pressed. This is a big advantage when making origami quilts and other origami fabric embelishments. You can even use it to put creases in paper when doing regular origami projects. The clover Hera Fabric Marker is a wonderful useful tool.
