Right, so, did a quick pleat up in the car, and conveniently had a pair of straight pins to fumble around with as well...

Sett width is 5 3/4" and based on red line to red line (not white, as I wrote above). This tartan seems like it keeps changing colours on me based on what day I look at it in what light...

From the *really* quick box pleating I did, I come up with a pleat face of 4" and somehow everything meets nicely and evenly under the face. I know some of the oldest known tailored kilts have box pleats up to 6," so I'm not feeling all too horrible about it, though I'm still slightly concerned...

(Incedentally, if this is better-suited to another forum, please feel free to move it).

Will try to post up a photo here of what I accomplished in half a mo, just have to get it off my phone and uploaded to Photobucket.

Thanks much all!
