Kathys is braided, and the one on etsy looks like macrame to me.
do you remember when we made the key fob things out of plastic,maybe back in the 60's or 70's? it had 4 strips of the plastic and they went over and under each other.then you pulled it tight, to make the knot..then you looped and folded it , over and under..usually a plastic bead or a wood bead was at the bottom or the start of it, with the clip..we made them in the summer when the schools had summer crafts outside.
