Yes I was speaking to the idea of a Kilt made to look like a flag and no9t to any of the various patriotic tartans. I like the American Heritage but if I were going to wear one of these it would probably be the American St. Andrews, simply for the bicentennial connection, my family is from Massachusetts and I was not that old in 1976, so I remember spending quite a bit of time learning about and visiting many of the historic sites int he area. I also heard a story as a kid that the tartan was designed as a gift to the American people from the Scottish people, although that may be urban myth.

As for the flag code not applying to anything that is not actually a flag, it has been applied that way before, although rarely. Section (i) covers other forms like embroidered or printed flags, although it is specific to advertising. and the full section (j) covers wearing replica pins in a respectful manner. Definitely the spirit (and I believe the letter) of the code would say that a blue apron/sporran with stars and a 13 striped red & white kilt would be wrong.

More to the point since there are 3 tartans pictured in this thread and at least 17 more found by another poster, there is probably no need for another general American tartan.
