On a warm, sunny late summer afternoon, my children and I made sheets, and sheets of watercolor paper. The pulp came from Twinrocker Papermaking Supplies in Brookston IN - less than an hour drive from us. The pulp was 100% cotton, and pre-sized for watercolor (that means a chemical was added to make the paper less absorbent). Each sheet was made individually on a small mould and deckle. The feathering on the edges was extremely pronounced and unique. We made them postcard sized - perfect for quick sketches on a vacation. I painted on a few after they were dry and was very impressed with the way the paints sat on the surface, and the irregular, non-mechanized surface added immensely to the charm of the finished paintings.
