So, I have finally gotten around to pouring some of the realistic water effect stuff into some of the river sections.
The stuff is pretty easy to work with, you just use it in thin layers. As you can see, I used some modelling clay to block the ends of the pieces so the liquid would not simply run all over the place. Then I set it aside to dry for a day.
After 24 hours, I poured a second layer. Again, let it sit for 24 hours.
It was actually more like 3 days before I got back around to these sections. I scored the ends along the modelling clay with a craft knife. Always use a fresh sharp blade - I probably keep the guys at X-Acto in business. Sorry about the blurry picture.
Now all you have to do is flock the banks, which I am going to try to get to this afternoon. Which means you may finally get to see some finished pieces in the next week or so. Note that I highly recommend you finish all of your pours and let it dry all the way before even thinking about flocking. The reason is simple: little bits of flock always get trapped in the hardening water. It isn't the end of the world, but it looks better without.
I have some custom pieces I need to work on to finish the project, and of course all that flocking and sanding and such. I hope to have a decent shot or two of some finished pieces by the end of the week. Until then, check out some of my other projects that I am updating.
