Any thoughts on creating the sort of thick moss that is seen on roof tiles throughout Northern Europe? Needs to be done in 1/35 scale.

I have done it using flocking for HO scale shrubs and bushes. You have to tear off small bits and place them in the cracks and low points between the tiles.

I have used the fine scatter material you find used for grass on railway layouts. I've used white glue, either as individual 'blobs' or larger areas then sprinkle the scatter material on and let it dry before brushing off any excess.

Then paint as necessary.

Ian,
I just bumped my thread called "This Old House" to the front in case you wanted to check out my roofs. It should be about mid-thread I think?

Thanks Jerry but just getting lots of black 'x's.

Ahhh..... photobucket is down for maint. That may have something to do with it.

One of the a/m companies (Lifecolour?) came out with a set a while ago with moss & lichen in it. That may work for you too

Here's Lifecolor's Moss & Lichens

Here's some local roof moss.
