There is always more to learn but I am pretty self-sufficient in many ways. Mostly food. I grow most of our food and make everything from scratch. I process our pigs and poultry, making the lard, bacon, sausage, etc. I grind any flour we use. I make all condiments and freeze, can, and dehydrate many, many items. I do some foraging, mostly for fruit. I make interesting country wines and meads with very little financial input. The only things we buy are single ingredient items, mostly, with rare exception. Chocolate it an occasional treat but I get the good stuff.
I'm working on my sewing skills, getting private instruction in fitting and have the goal of sewing my entire wardrobe eventually, at least something from every category, including outerwear and shoes. I will always buy socks, shoes, and coats, but will be able to manage if I ever had to, and I will have some of these items in my wardrobe. I am getting closer to that goal, am at the point where it is no longer non-stop frustration and I am turning out some really nice stuff, finally.
The biggest change since I was active here last is probably the beehives, and I switched all my gardens to the BTE method, using heavy ramial woodchip mulch. Free, of course!
