Sketchbook made a bit ago from file folders, which soak up the water too quickly for me. Since it contains island landscape water colors, I thought it would be a good sketchbook for watercolor kit & pen samples. I'll continue to make sample paintings from my other materials as time allows. I'm really enjoying the daily sketching, but need to be quicker at it. 1st sample painting took 4 hrs. & 2nd took 2 hrs., I'm improving & having a wonderful time. Enjoy!
