Well the jury is still out on my concept. I always visualized this with tall grass surrounding small waterways. To do this I have prepared the base with poly-filla and then glued random bits of teddy bear fur to represent the longer grass masses. Poly-filla was again used to blend the bases of the fur to the base and the tops were trimmed. The results:

Before I prime I have to get some colour into the grass. Unfortunately it is unavoidable but this will be the only paint that I slap on before the ground is primed.
After everything set up I thinned some acrylic paint and added a rinse aid to help it soak into the fur. This was dropped/painted/forced into the fur and combed out to separate the strands. Once dry I brushed it out again to make sure the paint did not clump the fur.
Here is where we are at the moment.

I have some more brushing to do to get the grass to look more natural.
