Exactly.

And here's the thing. One reason you hand-stitch a kilt is because you can more easily hide the stitching. Machine-stitched knife-pleat kilts are top-stitched and the stitching shows. But with a box-pleat put together how w2f describes, you can machine-sew the kilt and NO STITCHING SHOWS.... you get a straighter line in your taper and a stronger join.

Just my dos centavos. (I made mine this way).
