With only three thicknesses of material in the pleats, a regular box pleated kilt has less fabric in it than a knife pleated one (unless the knife pleats are unusually shallow), and the fore-and-aft weight distribution is much closer to half-and-half than with a knife pleat.

Matt Newsome at New House Highland is your go-to guy for box pleats, but I have a boxer that Barb Tewksbury made, and there must be others out there willing to make them.

Matt and Barb have written instructions for making a box pleated kilt, one of many sources of illustrations for different pleating styles.
