I've been doing some freeform painting with black gesso and watercolor. I learned this particular technique at a workshop I too with Laura Wait at Penland. We used all kinds of twigs, rocks and other found brushes to make marks on paper. It was one of the most freeing classes I have ever done.
I made some papers last night and then folded them into signature and made a little artist book. I still need to sew it together but wanted to show you my process.
