Boy, am I dumb or what??

Thanks Mikey.

Makes sense that I'd have to extend the length of the right hand straps to enlarge the circumference of the kilt...tightening them would just make it smaller. And extending the underapron strap would just pull the right hand straps away from their buckles....so three it is...

So NOW I think I get it....I think...probably should just get on with attaching them instead of thinking about it...
