Those are beautiful soaps. Are you able to find the remains of saguaro cactus? Do you know how they look sort of skeletal, kind of like sea sponges? The message mentions branches with moss, but if you're in New Mexico,, I think you should go with the local terrain (and I admit, I'm imagining Arizona and not sure what your climate is like). If you use a branch, I think it should be all bleached out, and also maybe some stones. Everything earthy beiges and grays except for the soaps. Maybe even some sand.
