Examples of wood faux-finishes from Higgins’ The house painter, or, Decorator’s companion
Higgin’s House Painter is a rare thing - it contains instructions for creating faux finishes for wood and marble, including formulations of paints and varnishes, as well as hand-painted examples (on paper) for each type of finish. It’s a marvelous period guide to materials and techniques.
What I love most about it, though, is that it was obviously a well-used copy. If you look at the sample for maple, it has a splatter of white paint on it, and the dark oak sample has scratches where the owner set something down on the opened book.
