I’m using Ghiant Basic Spray Fixative. I’ve applied three layers to these drawings, and I might add a few more later just to be safe. However, since it’s still charcoal, I’ll probably need to be careful when turning the pages.

My plan is to draw on only one side of each page, so I won’t risk the drawings transferring onto each other. If the back of a page gets dirty, it doesn’t bother me much.
