Greetings all,

I've been thinking of getting a modern-styled kilt for a while now, but as the prices of such things as utilikilts and such are a bit... shall we say 'high' for a garment I want to just try out, I've decided to make one. I've got a bit of sewing skill, and a fair knowledge of most of the basics of making a kilt, save one thing: every site I've seen gives instructions like 'Sew the pleats...', but I have no idea -where- you'd stitch. I like the look of knife pleats much more than box, and would really prefer to go this route, but I can't for the life of me figure which would be the best way to stitch.

Assuming that we're looking at the 'outside-facing' side of the pleated section of a kilt (you'll have to pardon the crude drawing and possibly incorrect pleat direction ^^;), which line would one stitch down to do a proper knife pleat- line A, on the 'outer edge' of the pleat, to hold it down to the one beneath it, line B, on the 'inside edge' to hold the 'inside edge' of the pleat to the layer above, or somewhere else entirely?
Any help on this would be most appreciated.
