It's hard to find a good marking pencil for black fabric. I found a white gel pen that works great. I test mark on a piece of the fabric before I mark the quilt and so far the gel marks have washed away. It's a very fine point and I can't even see the mark under the thread before I wash it even if it doesn't happen to wash out.
I use thee Sanford Uni-Ball Gel Impact pen, white color. For light fabric I use the Frixon pens. I don't go by other's guess of what will happen to the quilt in a hundred years if I use the pens. Who cares that much?
