Pleating option

[User]

Thanks for the pic. That explains the balanced sett (pretty obvious when you think about it). Any ideas on the casual pleat?

I don't think casual pleat is a well defined term. It's probably just used in common language. To me, I picture wider pleats in the 1" to 2" range as opposed to a specific pleating style.
But, maybe someone will chime in with information I'm not aware of.
