I've started the island using pink and blue foam. The picture will be the end of the island in kind of a layer so turtles can climb upon it. So far it is very simple to do. I cut off a foot of the 4x6 sheet and glued it on top using liquid nails. To make sure it sticks together I am also bolting it as you can see on the far end. To cover the bolt I use used a chunk of foam, glued it over the bolt and stressed it with the heat gun. From what I have read to get the rock coloring you start with a gray paint and then just sparkle it with different paint colors. We'll see. This is much easier then it looks. Just stress and cut the foam some and the heat gun does the magic. More photos later as I progress.
