My beautiful (and short lived) rushing river. Usually for moving water they recommend a second WS product that squeezes on, and then you rake it with a brush or what have you into wave shape. What I did here though was wait until the WS ‘water’ had partially dried, then dipped a fine paintbrush into white paint, and swirled it around in the sticky WS water. The result was rushing water far more authentic than what I achieved with the squeeze thing. As mentioned, the river was short lived – as it turned out, I did not have its elevation correct (needed to be lower), and the gap between tunnels, leading to the bridge to that concrete portal, was also too short. Live and learn!
