In a post like this, I always find it tricky to find a balance between providing a sufficiently good idea of the steps taken in building the costume and not losing people to inordinate details. It's tricky because the post attempts to synthesise the incremental steps taken over weeks and months (about two, usually) of hard work. Trying to exercise succinctness is challenging when you have one costume to outline; but this year there is double the workload to squeeze in. With that in mind, I'm going to try to keep text to a minimum on this one (and if I have skimped on anything, I'd be happy to elaborate in the comments if prompted).
