Leave No (Sand)stone Unturned

Was the back, now is the front.
Was front, now the back.

Like others, I Googled "sandstone" and also looked up some of the formations in a book, found a couple pictures I liked, chose the fabrics and threads, then just messed around with it. I was disappointed with it until I turned it over and looked at the back more carefully. The back actually looked better, I thought, so it became the front. And that also inspired me to call it "Leave No (Sand)stone Unturned."
