Washable graphite pencil not washing out - update!
 

Thanks to everyone for the good suggestions and the support. I did everything suggested and ordered the marking pencil remover. After three washings and hard scrubbings with bleach, it started to fade but is still noticable. I attached a picture but you can barely see it. I think what happened is that I didn't move quick enough with my FMQ and the stitches got squished and caught the graphite tightly inside them. First effort, oh well. So, I will quilt some decorative vine patterns to cover the remaining marks. I should have hand quilted it!!!

I'm so sorry for the difficulty you are having. The quilt is gorgeous though and I'm sure your friend will love it anyway. I'll bet that the graphite will wash out over time.

So glad to read this post. I was getting ready to use this pen to mark my quilt.
Your quilt is so beautiful. So sorry you had to go through all this.

Your ribbon embroidery is so beautiful. Sorry you had problems with the marking pen.

Oh my goodness, it is beautiful. And it looks like alot of time and work.

Your quilt is so pretty....it sure looks like you can work magic with your sticthes and ribbon. Good luck wit your cover up.

Your quilt is beautiful, I sure will not use this pencil.

I had the same trouble with a blue chalk pencil on a white queen size quilt made for my best friend of 30+ years. I finished up the binding in our RV on our way to Michigan to gift it to her and was mortified when it wouldn't come out. If I were you, I would keep working it a few more times, just don't dry it. I was finally able to remove the last of the markings with a paste of spray oxy + oxy powder and got under the stitching a little with a toothbrush. I also let it sit for several hours each time. I think it finally took 5-6 washings, air drying in between. Best of luck, it looks beautiful anyway!

Your ribbon embroidery is beautiful!
