Building these for the local Boys and Girls Club haunted house (working with Litemareb4xmas who is making the entrance sign to span the two columns). These stand 6ft 2in tall and are 15in wide. Made of 1x2 framing and 1/2in pink styro. Two coats of Dry Loc on one in this pic. I have just finished painting the second and aging the first so more pics on Monday.
A quick update, dry brushed and watered down black paint to add in water staining. Mossing is next with some feathering of an off white paint to the edges.
