I built a frame and filled it with foam having a raised portion in the middle upon which I glued the fort. I bought this fort back in Christmas 1994 in New Zealand on a visit there. I cut it in half to allow me to fit it to 2 two foot tiles. I found this unsatisfactory and embarked on restoring it to it's intended position, dominating a battlefield!
I sprayed it with Army Painter bone and gave it a hit with the strong wash to give a sand stone finish.
