The subject comes up periodically in just about every one of my art groups, of how to write on various media. Some pens just won’t write on some surfaces. One of the most difficult things to cover is watersoluble crayons. If you use them, and have tried to write over them, you know what I mean. A very thin application can usually be written on in pencil, Pitt pen, Prismacolor, oil pencils, etc. For thicker applications, about the only thing I’ve found that works consistently, without clogging, is an old fashioned dip pen and India ink.
