This particular kilt was started using an entirely different set of instructions, which lacks a lot of the features the X-kilt has. I've since scrapped that kilt and started over with a better material, along with the aid of the X-kilt manual. I also didn't read the entire manual until last night, so I have now found the section on edge stitching. I had previously not noticed edge stitching on many kilts, but I think I just wasn't looking for it.
