A woodworker will also just try stuff. They will also first lay out some specs and then start out to fill those specs. One step a time. While not TDD by the letter, many crafts work more or less agile, and more or less incremental. An example: I'm currently cutting down some 15 trees (Elms, died of Elm Blight). While it's impossible to cut down a single tree using TDD, I do cut them down incrementally, agile and in small steps: start out with the smallest tree (that stands alone) see how it reacts. Don't plan too far ahead, but plan a little - escape route, sharpen the chains etc. TDD wise: delivery criteria is "wood on a safe, manageable pile". (I halted the moment a funny little owl peeked out of one of the trees, annoyed. Apparently it was building a nest and I'm too late in the season. Also agile)
