I'm still working on my box pleat tartan kilt. I have the pleats in place but I don't know how to sew them. Sewing the box pleats on the inside is easy because it doesn't matter of the stitching shows - it will be up against the wearer. But, how do you sew the box pleats on the outside of the kilt so that the stitching doesn't show?

Anyone have any advice?
