Hmm... That helps put things together in my mind, actually. For best 'nonvisibility' I'd want then line B, with enough overlap on the pleats themselves to hide the stitching (I've not calculated pleats yet, but then again I'll be working not with plaid but with a decent weight dark grey somethingorother I've got about 10 yards of laying around). Now that I've got that last bit worked out, I'll start measuring and such tonight. Than ks ^^
