This is the sample base I did last night as a test. I'll probably do something similar to this for my Orc and Goblin figures. I may also use the gravel (Woodland Scenics Medium Ballast #B1379) on some of the larger Skaven bases as well, like the Rat Ogres. I need to get some of the smaller stuff for my pirate bases, to simulate sand. This stuff is a bit big for sand.
