My second attempt at a castle, much better than the first, mainly because I took my time with this one. A 2-day project, and I made it... just because... haha. 6- and 10-inch rounds, all Wilton buttercream (half-butter, half-crisco). 4 pounds of sugar just in the frosting! And still I ran out, otherwise I would've added windows. It was a good learning experience, and my niece and nephew loved it.
