Every kind of stone deserves its own wall.

I rarely post in this subreddit. As the title says, I built a unique 9×4 (or 9×5) wall for every kind of stone — though the granite one ended up being ten blocks long.
Could you give me some building suggestions?
(For the screenshots I turned on Vibrant Visuals, which almost fried my iPad, so I probably won’t be using it next time I make something like this.)
