Thanks. The ground cover is a mix of GF9's straw and arid static grasses. I use straight PVA glue mixed with a little desert yellow to keep it on the base and a static grass applicator (keeps the fibres upright) to shake the grass on. The darker grass is just Silfor tufts (a lot of companies repackage these), they're late winter tufts, 4-6mm I believe.
I've got some birch seeds that I plan to use on them all once I'm done with the vampires. They look like 28mm leaves. I was going for a late fall look.
