Getting started with the grouting. I used grout mixed with an acrylic extender, and white glue. Now, as it dries I guess I will know if this is going to stick to the float. I sure hope so. If not, I will have to try just straight silicone ....maybe. It looks ok so far. Time will tell.

I added some tiny Mother of Pearl seahorses also. They fit well for background. I used silicone to adhere them to the float.
