This is Chinese paper which is sold by Jacksons Art Supplies. The only bit I can read on the label says “Xue Shan” which I presume to be the company which makes it. The paper is very absorbent, has a shiny side and a dull side and has a vague stripe running through it (guidelines for their calligraphy?). I placed a piece on plastic on a slight slope. I dampened the paper and put very dilute blue paint along the top edge and watched it slowly make it’s way down the slope. Once this was dry I turned the bottom edge to the top and did the same with red. I really like the blending and the following of creases, I also like the way the paint went around air bubbles. The top photo shows the front (the side I painted) and
the lower photo shows the back. I think I actually like the back better.
