Which type of glue or whatever else one would use for this sort of deadfall. It must withstand a vacuuming now and then. I know the color is off on the groundfall in the second shot. I will be either airbrushing or painting in a more natural brown and relay the same.
Mark: Try using some Aileen's Wood Glue. You wouldn't need much and it's much stronger than white craft glue. It's also stainable, which helps immensely. Stay cool and run steam.....
