Back when planning this model, I thought I might make the roof out of something serious. Serious like steel. I reasoned the weight would keep the model from ever warping or trying to ride up. Over time, in my mind, I’ve retracted to something serious like styrene; it has no weight, but at least it won’t warp. Then, as the actual construction got closer, it’s now become card.
Card was just too easy: I set up the Cricut to scribe lines for 10″ boards, and then basically cut out shapes to match the roof. They joggle because they follow the rafters, and they joggle more because I accidentally flipped the middle one over while I was cutting it to fit. The whole roof is glued down with very tiny beads of white glue.
