So I thought I'd jump on the box-pleat bandwagon, and I had some tartan, so I started sewing one up. I got started on the last pleat and realized that there are a couple things I'm not sure about with box-pleated kilts, and was unable to find here. If anyone could point me in the right direction, I'd appreciate it.

a) Is there any form of steeking with a box pleat kilt, or is it unnecessary doe to not having cut out the excess pleat fabric?

b) How is that underapron strap attached on the inside? I assume through all layers of fabric with stitching not visible on the outer layer.

c) Is there any canvasing used, generally, or is that taken care of by not cutting the pleats as well? and lastly,

d) are the inside of the pleats stitched in any way, or simply pressed and held in place by lining?

Thanks!
