This is a stronger better quality jute twine used for baling hay in the old traditional rectangular bales. Comes in 2 or 3 mile spools. Get it at your local feedstore or farm supply house or just visit your local friendly farmer who will probably give you more than you can use. A spool should last forever. Any place they feed out hay should have piles of it laying around. Works great for shelters and will hold up for a couple of years if its not laying on the ground. Also works fine for tinder.
I like jute for fire starting also, picked it up at the local garden store. All of the baling twine I use is synthetic and doesn't catch a spark well at all. Try yours out before you really need it. I do wish baling twine would biodegrade after a few years since we use probably 10 miles each year.
