Mosaic Stepping Stones

For father's day, I figured we'd finally get around to using the stepping stone concrete mix I've had for the last year. First, Bastian and I broke stuff. He yelled out, "Destruction!"
Then I made the goop for Aleks, who laid out his pattern.
Bastian got interested. And mad that I only have one form so he has to wait til Aleks' dries to do his, tomorrow.
I'm not sure how this is going to work out. I've never done this before.
