Left side of a-shaped over apron?

I haven't looked at the x kilt manual in a while but I think you're actually talking about the right hand edge of the apron. I leave extra fabric next to where I mark the aprons so I can fold it over and hide the raw edge when I stitch the apron edge. I can upload a photo when I get home if that'll help.

i don't always taper aprons. If I'm making a kilt with a very narrow apron, say 10 inches, I don't taper it. The apron kicks out a bit and that's fine. Doesn't bother me and I explain it to my customers to make sure it's not an issue for them either.
