Does anyone have a solution for removing this ? This one was a "chalk-lead" in a Clover plastic pencil type marker holder. It comes with a container of half white chalk and half different colors. My daughter brought a quilt over for the 4th that she was finishing and she used the orange to mark the border design for quilting as she was going to use orange thread to quilt with. In a few places it is quite obvious and we tried brushing it off with a soft tooth-brush and rubbing with a fabric eraser, but several spots were very stubborn and she wet the toothbrush slightly. Well, it looked better until it dried and now it is a orange-tinged mess. She did not want to wash this quilt before presenting it but can't as it it. Anyone have a solution to get this stuborn orange off?
