I've started dabbling a little more seriously in natural media works again after a sustained run in digital. Materials in question for me are mainly pastel, watercolor, and pencil. However, I'm curious, what methods and mediums do you use to create your blinding or "pure" stark white (and not so white) highlights?
I've mostly used white India ink with a dip pen - but I've noticed how they tend to occasionally scratch the surface (sometimes good for texture... sometimes just leading to an unattractive blop of ink that needs to be blotted up)...
How are acrylic inks?
Opaque white and gouche?
Carefully applied bleach?
