The traditional way to make longer lengths of loop braiding is to work in pairs. One person holds the loops on their fingers and makes the move, the other person is at the opposite end of the yarn bundle and tightens the braid after each move. The method of tightening, by pushing with the blade of the hand, or pulling the strands out at right angles, makes a difference in braid density, and it takes some practice to get an even cord. It is handy as well to have another person helping for when the braider drops a loop. There are hiccups in the braid where I dropped a loop and accidentally added an extra twist.
I recruited my eldest to help me during a visit and we made 45 inches of braid in 30 minutes, which is more than I can make with a lucet in the same time.

At this point, I would choose the lucet method of cord making if I needed a long, strong, dense cord and I was working on my own. However, if I needed a known length, as for a belt or trim, and had access to help, the loop braiding is considerably faster and can make thicker cord.
