I made some streams.
(And some ponds.)
These are about an inch and a half wide and I made a couple of sections that will enable me to join them to my wider rivers that are about 3" wide. The tiles themselves have a nice faux-stone texture (see below). When combined with the gloss varnish the texture gives a nice ripple effect. The tiles are very cheap at about $1.50 each and they give you about 4 to 5 foot of river per tile depending on how wide you want your river. They are also very flat and can be bent easily back into shape if they warp in storage.
If you decide make some of these remember this: Leave the paper backing on the tile.
And here's the start of my next terrain project. A wadi.
I've been wanting to make a wadi for a long while and in recent weeks I've been trying to think of a way to do it. I've had several ideas and none of them seem workable. The main consideration are:
1. It has to look somewhat like a wadi,
2. It has to be portable and versatile, and
3. It has to be reasonably flat so that it doesn't impinge on a flat desert table too much.
