We just finished working on gouache resists in my class. If you would like to try this technique, I have described the process here. I have used this technique for a landscape, animals, and still life but had not tried a human portrait. I used a really interesting book titled “Facial Expressions” by Mark Simon. It is a book of references of hundreds of expressions done by people of all ages to be used as reference material. I want to try doing a family member in gouache resist. This was an interesting project and fun to do.
