Agreed. I don't make guitars, but physical crafts are a huge relief after writing code all day. I sew, knit/crochet, book-bind...any sort of craft that results in a physical object you can hold when you're done is immensely satisfying. And the repetitive motions of some of those crafts is great for getting in the zone with them. I find handsewing and crocheting especially relaxing. Knitting hurts my hands more for some reason.
