The moving blanket/prince and the pauper coat. I had made moving blankets from a silk jacquard we had woven for the 2012 A/W collection using 19th century map illustrations of Europe. One idea was that a prince had the enemy territory woven into a jacquard lining. He used the ticking side of the coat to be able to disguise himself as a pauper in order to trespass and embroider logistical notations by firelight at night.
I suppose the owner can make their own logistical notations, mantras or lists of loved ones.
