I have a big pile of fabric markers I am not very happy with any of them. I tend to use the Bohin ceramic pencil a lot. My favorite is my Frixion pens. I was told to wash my quilts with Orvis soap and that it will remove the chemical residue from the pens. My biggest problem is most of my quilts are made with both dark and light fabric. I hate switching colors of markers constantly as the fabric color changes. I have only used the Frixion pens on light fabrics. I use my Clover rolling chalk liner sometimes. If someone would make something that really works to mark quilts they could make a fortune.
