OCC Watercolor EM using pan watercolor

Back again to watercolor using pan watercolors. I am using the same colors by Cotman for all the samples, stamp purchased at Micheals for my grandaughter, and 4 different papers.From top[right side of photo]

 to bottom, the top sample I used children's watercolor paper, Premiere 140# Cold Press. The next sample I used Royal Langnickel 90# paper. next, Strathmore 140# Cold Press, and the 4th sample I used Canson 140# Cold Press paper. There is a difference in the texture of all the papers and also a difference in color of the Royal Langnickel 90# paper. The Premiere paper is inexpensive and has a rougher texture so that it required more watercolor to blend, dry brushing may work better or hard sizing the paper, and I did note that it seems to take color better with childrens Crayola markers.
