Well, I wouldn't say I'm an expert at anything (except griping and moaning when my arthritis acts up, lol). I knit well enough to create my own designs, I can crochet and sew. I'm pretty good at cooking, I can substitute ingredients on the fly if I discover I don't have a particular ingredient- and it usually comes out tasty. I have some knowledge of medicinal herbs and supplements. I can a lot- both water bath and pressure canning, as well as dehydrating and freezing, and getting my toes wet in freeze-drying. I garden.
DH is fairly knowledgeable about livestock and has a very good eye for conformation. And he's an excellent baker- especially long fermenting sourdough. He also just got his HAM license.
