I've been making a snow table for more scenery variety. I've been blogging the making of it on my star wars blog, since it was mainly created for things like snowtroopers vs hoth troopers for cold-weather star wars battles, but it will, of course, be useable for anything at all!
Just look at the January 2011 posts to see plenty of photos and stuff.
It's still drying, but being impatient, and quite loving the look of it, I've been sitting all my scenery objects and figures on it to see how they look. Anyway, here's some of the ruins castle walls and rubble, on the snow boards! As always, click on it for a bigger picture.
