I only use the shaker when I'm making trees. For doing groundcover, I find that a paper cup affords much better control: just tilt it enough to get the foam near the lip, then tap with your finger. With a little experimentation, you'll find the proper speed at which to keep the cup moving in order to get the effect that you want. And, as wickman notes, build it up in layers. I usually use one colour at a time, then vary the amount of each depending on the terrain: there'd be darker and more vibrant colours in ditches and other low spots where water would collect. You can also mix several colours together in the cup, but this usually results in a too-uniform appearance. Also vary the textures that you use: medium is good for most areas, but a light dusting of fine can add the suggestion of weeds just beginning to grow, as along the edge of the ballast. Don't be afraid to experiment with the colours, either. Too many people treat this operation as "science", when it's actually "art". If you don't like your first effort, when it's dry, go over it again.:smile:
