Because I'm modelling scenery which isn't spectacular by nature, I feel the need to spend plenty of time working at varying the ground texture on my layout. Here are a few of the things I like to use: Water putty to represent sand/mud... and with crushed shellgrit added... I wrap the shellgrit, available from pet stores, in an old shirt and I clobber it with a hammer. I save it, dust and all, in a container, then when I'm feeling really energetic I pound it finer with the mortar and pestle, ending up with this... I always paint it to match the rest of the scenery after it's glued down, because it's quite yellow.
Wow! H0 scale but applicable to all scales. Mikelhh has some great concepts in this thread. Why not add some of your own ideas? See the thread here. Additional search terms: scenery grass foam rock rocks
