Fantasy RPG Island, Part Three: We're Gonna Need Even More Green Stuff

So close, and yet so far. I have ordered a third package of green stuff. Hopefully that will be enough to fill in the remaining pits. Once that's accomplished, I can start adding paint and textures. 
 

Fantasy RPG Island, Part Two: We're Gonna Need a Bigger Tub of Green Stuff

I only had enough Green Stuff to fill in a few of the pits on my plastic island. I learned an important lesson: wet your fingers before working with Green Stuff. 

I read that it takes about 24 hours for this stuff to cure. This will become important when I finish applying Green Stuff, because it means I'll have to wait for that 24 hours before I start adding sand, rocks, grass, and other materials.
