My flat laces finally arrived from England, just in the nick of time before I go home for xmas. They aren't as wide as I expected, and are actually quite similar to the round laces Rancourt provided. I would not be surprised if they came from the same manufacturer that Rancourt sources their round ones from, because they are just that similar in color, texture, feel, smell.
I think I will go with the flat ones. Curious to hear what others think though?
Round Bottom - Flat Top
Round Left - Flat Right
