Having installed an aiglet on the lace today, I've put my finished dress to the test by wearing it about the house. The lacing went much, much more easily with the aiglet, and will take about half the time as sewing the dress up would. The lace and eyelets look handsome together, though the seam no longer extends straight down my front (oh, well) but curves around the breast a bit. The top of the lace doesn't need much in the way of securing, so I've just used a slip stop and tucked in the end; the loop left makes me want to hang something pretty from it, but I think that's the Viking aesthetic coming through.
Tried to get a photo of the finished seam, but it's dark as twilight out (it's lashing down rain) and none of the light in the house (or the flash) is good enough to get good focus...except for maybe the task lights, and they're down in the cellar for the great hole.
Lots of work, hopefully worth it.
