Good day survivors!
A nifty feature I felt was missing from Knox county was the classic sewing machine. Hand stitching is one thing, but tailors should be able to operate in style! I figure there would be two version:
An antique sewing machine that operates slowly. Uses thread more efficiently than by hand.
A powered, more modern sewing machine that operates with electricity. This model would be faster than an antique sewing machine, and use thread slightly more efficiently than an antique sewing machine.
A boost to helping those long tailoring levels out would be a blessing. While thread would still be hard to come by, or take a lot of work from killing and ripping up clothes, a sewing machine would let you more efficiently use what you find in the slow grind that is tailoring. Good luck out there in the apocalypse!
