This is exactly how the
F-H.C.A.G made her X-Marks "cheerleaders skirt" except that she put the tartan on the outside and the solid color on the inside.

It kind of makes me think of that old takeoff on "The Last of the Mohicans"

Brave came he with hands that never tremble,
tartan in hand and denim to assemble.
The denim on the outside and the tartan on the inside
to make himself an X-kilt for there is no real downside
to tartan on the inside and denim on the outside
for to make it all reversible and wearable on his outside
he makes the kilt on from two sides, always look upon the brightside
for the outside will be inside when he wears it inside, outside
and the inside will be outside when he wears it upside, downside.


etc. etc.....

I think I need coffee.
