I want to know if this paper size exists in the countries where each of you > live, ok? Can you easily find ordinary paper with those dimensions where > you live? And do they sell even bigger papers in those same stores? > > You can find different types of papers ( not too many!) papers in that size in my country - which is Iran. For instance print papers or different kind of Kraft ( This is what these brownish papers are called here) or Canson papers but I couldn't find Elephant hide ( any size) here.
Hope you got an Idea! :) Ali
