I just wonder if any one can give me their opinions on Clover chaco liner pen (Silver). I have a king size quilt I am hand quilting it with a lap hoop. It may take me up to a year to quilt this, just wonder if I mark this quilt with these pens will they wash out after being marked for a year or longer. I am using silver because the quilt is off white, pink and brown. The silver show on all the colors, and I am marking each section at a time.
Thanks
