Sorry, I wasn't as clear as I thought I was when I wrote working exactly the same / inside vs outside. I'm going to borrow a picture from a nicely done Charles de Blois arming garment:
Your cuisses are on the inside, and also tied on the inside (no visible knots on the outside). The lacing starts from the arming garment, and goes through the legs.
In this video, starting at 0:26 to 0:32, he has the lacing attached to the leather on the cuisse, and feeds that through holes in the gambeson, leaving the knots on the outside, but with the leg armor closest to the body, and gambeson outside. In this case, starting on the legs, and going through the arming garment.
What I'm wondering, from a historical standpoint, is there anything that says where the knot would actually be? And/or if the lacing is attached to the arming garment, or the arming tabs on the armor itself?
I know it's a very minor, and odd detail, but for some reason I'm really curious about it since I am re-evaluating how I suspend my leg harness for next season / new arming garments.
