Hugh,
The recent article on making rope by using plastic bags falls into the whole rope making category. A while back, when I still had animals, I made rope every day, a foot or two at a time, while feeding them their grain. I used the twine from the hay bales and made 8 or 10 strand flat braids. I regularly made 50 and 100 foot long ropes that I still use. They are as strong as a similar manila rope; I have pulled a car on the road with one. Learning how to braid flat braids is a skill that in a long-term SHTF event would be a negotiable trade skill and in the meantime think of the money you could be saving. – A.R.
