Nope the carpet is flooring carpet like they use in offices and such so its really ahrd wearing but doesn't shed like flock

The Trees are armatures done by woodland scenics they covered in tacky glue and flocked, then more added to get the shape. I saw some done recently with that whispy style of cotton wool you see at halloween, then sprayed with hairspray and flocked looked amazing.
Yeah we made this one a long time ago now so its a bit battered in the background you can see some more card scenary done by Worldworks i've black edged that takes a few hours to do but like you've said makes a huge difference in how it looks.
@Mike, we ahve a lot of scenary between use, resina nd stuff we've built so it would all weigh a huge amount. I reackon we could easyly fill a double garage with it all, it fills two rooms as is and is ever expanding.
