Hi Heathbar

As far as swing and hang go, it doesn't matter a bit whether you pleat it to the stripe or to the sett. As far as appearance goes, it makes a huge difference, because kilts pleated to the stripe look very different from ones pleated to the sett. And, if you don't do either one, it will look more like a kilted skirt than a kilt, because kilts are always pleated either to the sett or to the stripe.
