I know, and you can unravel the 7 strands into three even thinner strings that are very tough and thin enough to use as dental floss.

But my question is which one amongs the traditional types of natural cords and strings would be most appropriate for lashing, building shelter and so on. There's sisal hemp (bailer twine)which is used for bailing hay, linen flax string which is used for making bows, jute available from military surplus that when carbonized make a good charred cloth, cotton and hemp. There's also manila ropes, made from a plant in the banana family.

So far I think real hemp would be the way to go but where can I buy this stuff?

Thanks
