Could you point me to some tartan design site or separate programs that are easy to use? I don't want to design a new tartan, just make a minor change to one. Being 28 years in the Army, I love the US Army tartan, but being 28 years in the Infantry, I detest the gold stripes in the tartan "for the cavalry." I'd like to know what the Army tartan would look like with the gold stripes changed to Infantry blue
