I can't believe it. I traced my quilting design with a pencil. Pinned the tracing paper to my quilt and stitched. Never even THOUGHT about the graphite - which came thru with every needle stroke. Now my white thread is an ugly dark gray.
Google tells me to treat with ammonia, then launder. But I can't wash an unfinished quilt sandwich. Will it wash out later? Someone somewhere HAS to have made this error before. Puh-leeease tell me it will be OK.
Meanwhile, how do I mark the remainder? I avoided ballpoint, thinking it would do the same thing. Maybe quilting pens work on paper?
