Number of casts: too many to count (I'd estimate forty). Difficulty: Hard. The castle is one of the largest pieces I have done to date. The whole thing weighs probably fifteen to twenty pounds, and is nine inches high. The lower and upper platforms had to be reinforced with foamcore struts because the blocks couldnt' be suspended that far on their own. I am very pleased with how the whole project came out, despite several minor flaws. I like how the circular towers merged with the straight pieces from the Wizard's Tower mold. A great paintjob made the castle one of the best pieces to date.
