I thought about making some of my own clump foliage from foam, there are many tutorials out there and to be honest I was a little intimidated.
I took some kitchen sponge pads with the rough green on one side and tore them up, minus the green side. I then blitzed in a blender with some water until it was the desired size.
Once dry I mixed up some different greens and added to the sponge mix, after it was dry I had my own clump foliage.
It was a very easy project, I recommend you make your own today.
I will show you these on my next terrain piece, the clasic warhammer hedge and fence combination.
