I am making Window 176 and need a source for the arched crown shown in the sketch. Can you tell me where to get it?
Conso® has discontinued the one represented in the book. Try the following:

Another idea for Window 176 is to make a small bowed cornice to use as a mount board. It is easy to make using bendable plywood.
