In addition to the Carolina Tartan, there is a Confederate Memorial Tartan. From Scotland Forever:
“The Confederate Memorial Tartan is woven in Scotland and serves as a tribute to the soldiers of the Confederacy. The tartan combines Confederate grey with the colors of the battle flag. There is also a yellow stripe representing the cavalry, a blue stripe for the infantry, and a red stripe for the artillery.”
At the NC LoS conference, there were some Confederate Memorial Tartan scarves for sale.
