Very good ideas, I hadn't thought of removable pieces to put onto a large piece.
Cheers

If you do the doughnut templates (with the removable centre) they give you many more options to go all out with density and detail. For brush, I used rubberised coconut husk covered in flock as undergrowth in my forest templates.
It is the material that is used in wrought iron planters similar to this.
If you look in the local dollar/pound store it is usually in the home décor isle. I prefer it becasue it does not dry out and cannot go mouldy. For flock I used the sawdust flock method.
Hope that helps and gives you some more ideas.
