I was disappointed. I used pencil on my String-X quilt and it washed out completely. And I'd sampled pencil on some of the fabrics in this quilt and they washed out. I know nothing about the chemistry of pencil on fabric. Maybe some fabrics soak in the graphite, or maybe the longer the pencil is on the fabric, the harder it is to remove. It doesn't matter. I would just rather not have pencil lead on a finished quilt.
Being the sensible sort, I did not panic. I got online and searched how to remove pencil marks from fabric. I found many suggestions. I tried each then washed the quilt and air-dried it before trying the next. Unfortunately none of them were completely effective.
- Goop. It is my go-to stain remover and nearly never fails me. Chances are it would probably remove pencil from jeans (where it matters much less than it matters on a new baby quilt!).
- a white eraser. That was a big mistake. It rubbed the fiber the wrong way.
- liquid hand soap which had no effect whatsoever.
- a mixture of water, alcohol, and dish soap as recommended at Quilt History. It was ineffective.
- Fels Naphtha rubbed on the marks. It had no effect.
- ammonia. This may have lightened some of the pencil lines but did not remove the darkest of them.
- Lestoil. This may also have lightened some of the lines but also did not remove the darkest of them.
Still, I implore you for the sake of your quilt,
Please do not use pencil to mark quilting lines!
