Marilyn Swartout asked for suggestions on marking pencils for the MB pleats. I told her my suggestions for chalk markers, mechanical pencils, and soap slivers, but she had a better one. She said, "Also, when marking I grabbed a charcoal pencil that I use for painting. It worked wonderfully - seemed to show up on light or dark fabric and wiped right off. This is what is written on the pencil "Generals Pastel Chalk 4474 Dk. Grey." Gotta try it!
