Sometimes you need some cord and one fun and fast way to make one is fingerloop braiding (for tutorials see Links below).
It is a medieval technique and I used it several times with good results.
On the photo you see two of my self-made cords.
The most difficult part is for me to get the cord evenly, because you must adapt to the loops become shorter while working.
But it is only a question of practising ;-)
