marshall oil pencils... pre-coat?greenspun.com : LUSENET : polaroid transfers : One Thread
I'd like to know whether to use a pre-coat of PMS solution when using Marshall oil pencils on watercolor paper? I know it is necessary when using photographic paper, but I am not clear if this is the case for watercolor paper as well.
Actually I've been using these pencils without a pre-coat and they seem to work great! I wasn't sure if the oils can harm the paper fiber, as oil paints might.
