You have to try this stuff! Go to an art store and ask about it. I forget the name. But if you're looking for more texture in your paintings they have this stuff you paint on, it comes in different grain sizes and textures, but you let it dry then you print on that and it makes textures like big wood bark, or small wood grain, or kind of like concrete.

Also different brushes can make all sorts of different brush strokes of you go back over wet stuff with. Clean brushes🤷🏽
