Paper is the support and source of light for a painting .
Yet, with the exception of a single book , there are no test based comparisons of watercolor papers of the same kind that are made for watercolor paints. So I adapted or developed my own paper tests to evaluate how the papers would respond to typical watercolor use. The sampling here includes sixteen of the better mouldmade brands and a few notable handmades or historical papers. No Japanese, Indian or other non-European papers are reviewed here because it would have been overwhelming to learn them too. I hope to try them someday.
