I'd like to think I could, and I've certainly been practicing. From knitting (my next project is to learn to process wool from sheep to scarf) to tanning animal hides, preserving foods using natural methods, growing my own food (and tobacco! :) to the honey wine I have brewing and the primitive weapons methods I've been working on and more. I've got a helluva lot more to learn, but I make sure to practice each skill set I do learn. I get a lot of strange looks from people these days. I don't really care.
So keep on practicing, and ignore the funny looks. You got skills. One thing that can never be taken from you.
