I went over to Robert Moses State Park the other day. I hadn't sketched the Fire Island Lighthouse in a while. Parking so that I was facing the dunes, I dug through my beach bag only to realize I couldn't find any paper that was really suitable for watercolor. I finally gave up and used a sketchbook that is barely suitable for ink so needless to say the paper buckled. At least it didn't pill.
I moved the car a little...those clouds were calling me. I used the other sketchbook I had with me. The paper was a bit thicker so it didn't buckle quite as much. Of course later when I was sitting on the beach I found that I had a few small pieces of watercolor paper in a baggie in one of the front pockets of the beach bag. lol
