This is my fourth ever painting (also fourth Bob Ross painting). Gift for my dad for Father’s Day. The clouds were very frustrating! Does anyone know where I can get the blender brush he mentioned without having to buy a whole set of Bob Ross brand brushes? I looked at my local art store, they don’t have any Bob Ross brand stuff, and the blender brushes they had were synthetic. This was also my first try on an actual canvas, vs. the cardboard that comes with the Bob Ross starter kit.
