Inspiration for this board was found on one of the cards from the LotR Living Card Game from Fantasy Flight:
Another source of inspiration was Bruce Hirst King's Hall piece for D&D games.
I used for this project Hirst Arts Molds # 42, 45 (gothic dungeon blocs), 205, 201 (floor tiles) and 85 (accessories: also good for objectives).
Having cast using Durham Rock Hard Water Putty enough blocks, dried them in the oven and sorted them out, I was ready to start construction.
I started to glue the tile pieces on a 1/2'' thick pink foam board that was 1 foot x 1 foot:
With all the pieces glued to the foam board:
Then, to add a more finished look, I glued around the base some wooden decorative borders found at Home Depot in the ceiling molding area. Then I filled some of the gaps with filler and applied Gesso on the back of the foam board to add some durability (bottom side of the board):
Next step: painting!
