Advice few sewing box pleats?

[ardchoille]

Ok, I think I've got it:

lay the material out flat and mark a line on the inside of the kilt every 3 inches, do this for the entire pleat length. Fold the material between each line you've drawn so that the first and second lines touch and stitch the fell along that line on a sewing machine. fold the material again so that the third and fourth lines touch and stitch that down. Do the same for the fifth and sixth lines and so on for the entire pleat length. When you're done you will have material with loops every three inches. Lay that material out with the loops on top and press the loops down so that the edges of each loop are touching the edges of the neighboring loops. When you turn the material over.. viola.. box pleats with the stitching hidden on the inside of the material. The inside pleats can be hand stitched and the stitching will not be seen from the outside of the kilt.

This looks like it will work and it will cut a lot of hand sewing. It will hide all stitching and form much better stitches than my skills will allow. Of course, the 3 inches should be adjusted for the width of desired pleats. My friend even did this on a scrap piece of cloth and it looks awesome from the outside.

Can someone comment on this technique?
