Artificial grass

[Democritus]

Hi Guys,
I’ve turned a couple of ‘birds’ following Collin Way’s idea. Attached. You will see that I have scattered artificial grass on the mount, but it keeps flaking off. Is there a way to fix it so that it doesn’t do that?’

is this the sort of powdered grass they use on model railways? you could maybe try a spray varnish
