Gradually, I started to figure out ground cover techniques and began to get something I was happy with. I also applied the first few coats of the WS water, and it began to come together.
The only problem – the WS water, although it dries to a hard surface, *is* a liquid when you first pour it. Since I had essentially bisected the river, placing it to the facing edge of my Othello scene, I had to do something to stop the water from simply running over the side before it dried. This resulted in using caulk, but even that wasn’t enough – there were always places the water found to drip out of, requiring many applications of caulk, toilet paper, or anything else I could find to plug leaks. 🙂
