Okay, so I'm done with this Vandor Mountainside. It didn't turn out as well as I'd like, but the main focus will be on the Swoop. I ran out of foam board, so it'll have to do.
So basically I cut the bottom and back of the mountain out of foam board. I cut out a square on the bottom to insert the battery for the swoop. Then I attached a plastic tube to both hold the swoop and run the wires to the battery. Then I filled the bulk of the mountain with foam and charcoal. Then I covered it with sculpting plaster and plaster cloth. Then I sculpted the plaster, to make it look Rocky. Then I used Woodland scenics watercolors for the rocks. Then I mixed glue, water and woodland scenics snow shaker, to make the snow.
