Thanks. I wanted to give every piece of terrain, even solid stone more than just grey tones.

The leaves come dry and precut. I'm not exactly sure what the material is, but they are crunchy like real leaves. I have jars of different colors. To give them durability I mixed up water and PVA, and mixed them leaves in to make a kind of leafy paste. There's some green micro flock as well which I mostly add separately but if a little mixes into the leaves adds more variety.
