Thank you, Peter. Your paper is most informative, and it (especially the illustrations) confirms some of my ideas of how to make a drawstring plaid. I presume that the same technique might also have been used to make an early 18th c. drawstring feileadh beag. Although none of those has survived and reenactors obviously can't document the practice, I think it is logical to assume that a feileadh without the pleats sewn in would have been donned the same way.
