I love the Golden Threads paper. I mark my design with a mechanical pencil and pin it to my quilt. I also wear the Machinger gloves so I do get graphite from the pencil on the gloves. So far, I have not transferred any of that on a quilt top but I have a 2nd pair that I can change into when I'm back working on the fabric.
I have been burnt too many times with marking pencils that do not come out even with testing them first. I also like the Bohn marking pencils but have not used them much for marking quilt tops.
Thanks for the video.....it was interesting.
