"Flexible/modular river tutorial" Topic

I made a guide on how to make rivers that can conform to any surface placed beneath them. Also I demonstrate how shower caulk can be used for water effects. Check it out below:

Neat idea, thanks for sharing it.

That came out great! I like the water effect with the plastic bag trick. Since it takes so long to dry, I wonder if you could go over it after a few hours to pull more of it up to get the effects of shallow rapids?

How flat do the edges sit after all is dried? I have tried this one time before and the edges started to curl up and towards the middle of the river. I'm sure I was doing something wrong or using the wrong product.

Just what I have been wanting to see a tutorial about.

Thanks for posting that, your river looks terrific.

I'm sure you could continue to work with the caulk to make some impressive waves, I'll have to give that a go sometime.

It lays pretty flat, I find the key to dealing with caulk is to make sure all edges are pinned down until it drys. I also reinforced the back of the river with duct tape to help fight against warping. Placing larger stones at intervals along the river also helped guard against warping.

Great stuff

Question for you – you mention on the video description about lining the back with caulk to prevent warping. Did you use the clear or the white? The whole length/width? Would you do that before painting/flocking?

Just simple pins to hold it to something for drying?

Think he uses the white. It's what I did and works like a charm.
