One thing I would like to use this journal for is to share different materials that we have experience with or materials we would like to experiment with.
In the last few years there has been a surge of cementitious wall panels. The most recent find is a UK company called Rock Panel. Specifically i have been looking at Rock Panel Woods. It seems (at least from photos I've seen) to have a nice variation in the panel colors. Most of the time when you find 'wood' finishes there is a definite repetition in the panel colors that would never happen with real wood. I think it might be worth some investigation time.
