I have some of the old GW lush type grass and want to use this in developing a very grassy basing scheme - not the more patched affair you usually see but rather predominately grass, something you might imagine on a Maiden World. Obviously it can't be 100% grass as that will look weird, I have some 6mm flowers to spread around and can look at little stones and the like for rocks to spice it up - I'm stumped on what goes under the grass.
I don't want it to be completely flat or look lazy by going straight on the base, but I can't figure out what will work. I've thought about some modelling sand but it might make the grass appear too high next to the model? Or should I be looking at one of the texture paints?
Any help would be appreciated, all the more so with examples and such
