If the zombie apocalypse gave me adequate time to get what I wanted (and there was no electricity), I would bring my hand crank Singer 201 portable (a beautiful lotus design!) along with size 12, 14, and 16 needles and a bunch of bobbins and thread. Pins, scissors, rulers, machine oil, buttons and other fasteners, and some seam measuring items.
Come me to think of it, I really do need to get that beauty out and put her through her paces.
