We now have all four of these in use. Ce we try and figure something out since according to wiki, both neckerchief and headkerchief are pretty much bandanna with specification of where its being worn?
We currently define "bandanna" as either around the neck or the head, while neckerchief and headkerchief are specific places. Could we consider just invalidating bandanna away in favor of the latter two? With headband taking up the slack when it's not clear if it's a square, triangle or band of tissue.
