Yeah, thanks for the information carrigton. It seems I got the wrong glue.  
But for the time being, the grass holds fine. I will buy the waterproof glue for the next hill, though.

Thanks Nico, glad you like it. Well, I used maple bark, since the pine bark was only available in 120 l bags.   I think it works well when you want a rather grey granite look for your rocks, but I will get some pine bark next time for variation.

cheers

Nice Hills, I can't seem to do the same for what ever reason, my hills always seem to come out looking unnatural....all i can do is keep trying though, would complain if someone had pictures of all the different stages of hill making, would help a brother out
