If things did go t*ts up , then footware would be one of the things I would soon run out of . I don't have enough money top store loads of things like that . But if it was that bad I would go foraging for what I needed
I have enough knives anyway , but if I needed more, I could make what I needed in the forge,out of scrap metal.
Instead of protective paint I would grow linseed , both for the oil and the fibre . Oil would treat timber etc and the fibre would go to make yarn for sowing and for making linen for clothing . This I am doing anyway , end of the world or not !!!. I will also be growing hemp for fibre and oil . Oil for health and cooking , fibre for clothing , sacks ,string , rope etc . Beeswax from my beehives will supply all I need to waterproof any clothing and it will also stop tools from rusting and polish any furniture should I so wish . Grease would come from sheep and pigs etc . It has all been done before , and is all still out there and easily available . It is just us that have forgotten how to obtain it , we are so used to buying everything off the shelf .
