FWIW- Just looked at the Wood Mag shop tip of the day about using white carbon paper on dark woods. As a Blacksmith working black iron sheets and plate, I often used old brown paper grocery sacks opened up and the back side gone over with white soft chalkboard chalk used on edge, or putting a light coating of chalk line chalk or just soap stone that I scraped off a stick with my pocket knife all over the area where I wanted to trace a pattern, lay the paper carefully on the plate, trace the pattern then gently blow off the excess and the pattern was left where the chalk line powder was pressed down by tracing over the pattern.
