After weaving, concerns about unraveling come to the forefront. To finish the raw ends of the scarf I made 2x2 twisted fringe, then realized that left a tail on the selvedge. Oops. Next time I'll hide that within the weaving.
Some people enjoy twisting; I don't, and can see why people use a hair "braider" for the task (did not know there is such a gadget). By beginner's luck, although the pattern as written has the wrong number of ends for 2x2 twisted fringe, my mod added the right number of ends for the fringe to work out perfectly. I left long tails on the fringe on purpose.
So, the scarf is ready to wash!
