I'm leaning toward the warm toned "Rustic Ranch" flag stone to be placed on top of cool toned 2" "Missouri" gravel base. I like the contrasting colors to define different elements.

Meanwhile, I hope that the landscape designer wrote my choices down. While we were walking around, she more or less ignored me. During this visit to the stone yard, she instead constantly walked ahead with my husband and only talked to him. I couldn't hear what they were saying. Taking photos to be able to later consider what I'd seen, I couldn't catch up to them as they raced around. Nevertheless, I did tell her my choices before we left the landscaper's storage yard. I just don't know if she listened to anything I said... I haven't seen her in person since this day.
