Cool.
I like tying knots too. Macrame was probably invented by sailors (nobody seems to agree which or where, but probably either Arabs or Portuguese). They used to tie knots when they had free time on board, and then sell items when they reached port.
It became a Victorian lady's hobby.
I remember it from the 1960s, when it was a fad. A lot of the products made were totally useless. I particularly remember "wall hangings". Also, coarse unisex hippy-wear that was too loosely tied to provide any real insulation (presumably totally "decorative").
Also remember a lot of really ugly purses.
Some useful items include SHOPPING BAGS. I live in a city constantly threatening to create a bag tax, plus a lot of merchants now charge for them anyway, or at least pressure customers to bring their own.
Fisherman's nets are tied a different way, that calls for a shuttlecock doo-dad and a frame to keep tension. However, you can fake netting for items like net bags by using multiple strands and tying them with either overhand knots or, for better symmetry, square knots. It is basically a macrame technique, starting with larks-head knots around a cord at the bottom of the bag, which you will later tighten into a tight loop.
Another useful item, that can be tied a number of ways, is a hammock. Note that a hammock needs to be significantly bigger, with more slack, than most people realize. Otherwise, you tumble right out of them. Something about center-of-gravity.
Not macrame, but fairly useful, is flat-braiding. You can make a lot of items out of various braids and sennets.
